If you do your computer and network maintenance, let's take a look at this post, you will find that there are a lot of tips that are worth collecting and use and learn.
Article 1: Windows 2000 Connection Sharing Interner Connect Share ICS Sharing can be set to 192.168.0.1 first set to 192.168.0.1 successfully changed to you want, you can. (From the unparalleledity) 2: Merge MP3 file. COPY is a very important command in DOS, which is cleverly uses its parameters / b to implement the features that merge several files. For example, you want to combine the A.mp3 and B.mp3 under the D drive into C.mp3 and save to the E disk, you can do this: Enter the MS-DOS mode, type: C:> Copy /Bd :a.mp3 D: .mp3 E: C.mp3 and then enter the car, the merge speed is fast! With this characteristics of COPY / B, you can also connect .WMA,. MPEG, .avi, .dat, multiple audio and video files, etc., both simple and convenient. Article 3: Command line to change IP C: WinntSystem32> NetshNetsh> InterfaceInterface> ipinterface ip> set The following instructions Check: Set Address - Set the IP address or default gateway for the specified interface. SET DNS - Sets DNS server mode and address. SET WINS - Sets WINS Server Mode and Address. Article 4: Easy to control the "System Configuration Utility" under Windows 98 is a high usage tool, which can easily delete or temporarily stop certain launches, but use NT kernel Windows 2000 But there is no similar tool. It doesn't matter, you can copy the msconfig.exe in the original Windows 98 installation directory (in the System subdirectory) to the WinntSystem directory of Windows 2000, then run directly. The program first pops up an error message box, prompting the following system files: config.sys, autoexec.bat, system.ini, and win.ini, this is normal, these files do not need this file in Windows 2000, ignoring this error That is, you will see the familiar "System Configuration Utility" window after clicking "OK". Article 5: Win2000 / XP and WIN98 Interpuna If the two computers use the Win2000 / XP operating system, the establishment of the LAN is a very simple and easy thing. When the hardware connection is completed, it can be immediately in the online neighbors. "Seeing each other. However, if there is a computer in the LAN where you use Win98, it can be not necessarily, we often find that although the ping command can pass, but still unable to implement an interview in "online neighbors", what should I do? Countermeasure 1: Enable guest users in Win2000 / XP. Two user accounts are built by the Win2000 / XP system after installation, that is, Administrator, and Guest (guest account), all users who are not assigned to the account will use the guest account by default, the account There is no password. However, under default settings, this guest account is not enabled, we can find the "Guest" account from "Control Panel | Administrative Tools | Computer Management | Local User and Group | User", and right-click "Guest Property dialog, removing the hook tag on the "Account Deactivated" check box here, which can be accessed from Win2000 / XP from Win98 after exiting.
In fact, after the Guest account is enabled, the biggest benefit is that the username and password are not needed from the WIN98, which is more suitable for the user's uncertain, a large number of visitors, but for home users. Speaking is not applicable. -------------------------------------------------- ---------------- Countermeasures 2: Check if there is security policy restriction in Win2000 / XP. Sometimes Win2000 / XP "smart" overhead, although we have enabled guest accounts, from Win98 but still unable to access Win2000 / XP, then from "Control Panel | Management Tools | Local Security Policy | Local Policy | User Right Assignment Find "Access this computer" or "Reject this computer from the network" or "Reject this computer", then check if a guest account or other corresponding account is displayed, and then add or delete it according to different situations. -------------------------------------------------- ----------------- Countermeasures 3: Deactivate the firewall on the local connection. The firewall is a security system that acts as a security border between the network and the external world. Microsoft provides users with a built-in Internet Connection Firewall (ICF) in WinXP. After enabling, some unsafe information can enter the internal network from the outside. However, if you enable this firewall in your local connection, you will cause you unable to visit each other, "XXX cannot be accessed", "You may have no permission to use network resources", "Please contact this server Administrators contact similar prompts such as visiting whether you have access, "Can't find the network path", at which point local connection is disabled. -------------------------------------------------- ---------------- Countermeasures 4: Add NetBeui protocol for WinXP. In fact, directly adding the NetBeui protocol to solve the problem that the problem that cannot be visited is sometimes more simple, and it can solve the problem of the enabled firewall mentioned above. The NetBeui protocol is automatically installed when Win98 is installed, but since WinXP no longer provides technical support to NetBeui protocols, it can only be added manually. Find the WinXP installation disc, enter the "ValueAddmsftnetBeui" folder, here there is nbf.sys, netbeui.txt, netnbf.inf a total of 3 files, first copy the nbf.sys file to the "WindowsSystem32Drivers" folder of this machine ( The native refers to this unit is installed in WinXP), then copy the Netnbf.inf file to the "WindowsInf" folder of the unit, NetBeui.txt file can be available. However, INF folders have hidden properties, and users need to select display files in WinXP "Tools | Properties" windows to see this directory. -------------------------------------------------- ---------------- Countermeasure 5: Enable "File and Printer Sharing" in WIN98. This is a problem that is very simple but often ignored. It is a machine with Win2000 / XP. Although it can find Win98 machine from "online neighbors", it is impossible to access, because Win98 is not enabled "allowed" This option can be solved by other users to access my files. Of course, in addition to the various reasons mentioned above, two computers are not in the same working group, or have conflicts in the internal IP address of the two computers, even HUB failures, line failures, etc.
Article 6: Plus a default before Windows startup service, Windows 2000 Server doesn't have to log in to launch the service, which is unfavorable place, not full security. Use the syskey command to add a lock before starting the service, (think of it, you can no longer be canceled, from the CIW book) Article 7: WindWos 2000 automatic login Normally, users must be on the login interface Enter the username and password after entering the username and password to be entered in Chinese Windows 2000. However, Chinese Windows 2000 also provides functions that automatically log in at a set of usernames and passwords at startup, so that you can automatically log in without manually entering usernames and passwords. It is worth noting that it is best not to set the automatic login system mode (especially if you do not set up an administrator authentication system). The operation method of the automatic login system is implemented in Chinese Windows 2000: Select "Start" "Run" and enter "regedit" (or enter "regedt32") and open the Registry Editor. Located to "HKEY_LOCAL_MACHINE SOFTWAREMICROSOFTWINDOWSNT CURRENTVERSIONWINLOGON". Double-click "DEFAULTDOMINNAME" and enter the domain name to log in (for example, "PCW" in the "Data Numeric" field in the "Edit String" window, and then click the "OK" button. Double-click the "defaultUsername" numeric name, and enter the username where you want to log in to this domain in the "Data Numeric" field in the "Edit String" window appearing, then click the "OK" button. In the right window, click the right mouse button to select "New" * "String Value", name the new string value to the numerical name of "AutoAdminLogon". Use the left mouse button to double-click the "AutoAdminLogon" numeric name, and set the value to 1 in the "Data Numeric" field in the "Edit String" window, then click the "OK" button. In the right window, click the right mouse button to select the "New" "Winding Value" command item, name the newly created character value to the value name of "defaultwordword". Use the left mouse button to double-click the "Defaultword" numeric name, and enter the user's login password in the "Data Numeric" field in the "Edit String" window, and then click the "OK" button. ---- Exit the Registry Editor window, restart your computer, then log in with this username, and no longer need to manually enter the username and password (if you have left the Shift button during the login process, you will A dialog box that appears to enter the username and password). If you need to cancel the automatic login function, just place the current subkey position here with the mouse option, and then modify the AutoAdminLogon key value from 1 to 0. Article 8: Do PAT1 with the Windows2000 NAT, add the NAT protocol. Right-click "General", "New Routing Protocol" 2, select "Network Address Translation (NAT)" in the "New Routing Protocol", click "OK" 3, so many in "IP routing" A "Network Address Translation (NAT)" 4, right-click "Network Address Translation (NAT)", add "New Interface" 5, select "Internet Connection" in Network Address Translation (NAT) "( That is, connect to the connection to the Internet, don't choose wrong) 6. Select the "public interface connection to the Internet", check "in the Network Address Translation -InetNet Connection Properties" Convert TCP / UDP header (recommended) "
7. Add the start address and end address you need to provide port redirection in the "Address Pool" option table. (Also 7. All IP addresses you have to engage in port mapping, usually we will be an IP address So you don't have to talk about the difference between "Address Pool". It is assumed here to set the following: This is the following: 8. Provide the data connection you need to orientation in the "Special Port" option list. Agreement (Is TCP or UDP protocol, such as web and ftp are TCP protocol), after selecting "Add" 9, "Add Special Port", here is the core of setting the port mapping, map which port of the NAT host is mapped to Which port of the network host is set here. Since the "address pool" is provided, you can add any address in "Address Pool" in "Public Network Address". He is added "192.200.200.3",
Is my address, if you don't set an "address pool" in front, "In this address pool item" in this option page is not available, you can only choose "In this connection",
That is, you only have a public IP address, which is more suitable for only one IP friend, can do not have to do excess settings without "address pool"? If there is a problem, it is not a trouble. "Incoming Port" is the port of the NAT server with public IP from the Internet, and is set to 8080. "Special Address and Outlet Address" is the IP address of the internal host and a port that provides special services, which is mapped to 8080 ports on 192.168.0 to 80 ports on 192.168.0.2. This is the redirection of the TCP protocol port, as for the UDP orientation page, the following figure is the case after adding the port mapping. IV. Test results at 192.200.200.55 Test the web server built on the WEB server on the NAT host and the intranet of 192.168.0.2, and the results are as follows: (Sorry, the middle changed the port number, 192.200.200.3 8081 port mapped to 192.168.0.2 80-port) Article 9: Use the installation disk to repair GRUB (confuse me for several years, today solve ^ & ^ ") 1. Problems to solve this solution: We may be When WIN is installed, the GRUB or LILO is cleared from the MBR. If there is no system boot floppy disk with only the installation disk, the solution is taken. There is also a way to use an upgrade system for the Upgrade system. This method is extremely unreliable. After nearly two or thirty-ten practice, we prove that there is almost very few, this method is used to not install GRUB or is also possible. If you have installed the GRUB installation, later reinstall the LILO with the Window or other operating system, it will not be able to guide the system normally, which is invalid. Therefore, this program is best suited for GRUB recovery. Second, the resolution process [Take RedHat 7.3 as an example] 1. Put the first place of the mounting disk in the optical drive, then restart the machine, and boot the system in BOIS. 2. After the installation interface comes out, press the [F4] button, which is Linux Rescue mode. 3. A series of keyboards and several simple formulations, [Continue] afterwards. . . This process, I don't say it, it is relatively simple. 4. This character SH # 5 will then appear. We can operate GRUB. . . what. . . As long as there is such an example, it is a small Kiss, I just don't say, no one can understand, the earth people know. . . . SH # GRUB will appear in the character grub> We can enter the GRUB> root (hdx, y) GRUB> Setup (HD0) if successfully there is a successful ... here X, If it is a disk, it is 0, if you installed Linux's root partition on the second hard disk, that x is 1; Y, is the root partition where Linux system is located. Setup (HD0) is to write GRUB to the MBR of the hard disk. Let me give an example, if I take my hard drive as an example. I installed XP on the first hard drive, put RH73 in the first hard disk. I have two hard drives. If I lost GRUB, I used this way to find it.
If you don't know which partition your Linux is installed, that is, don't know how much this is, this is not tight, first enter root (HDX, then use [Tab] to view, you will understand ... As follows: [There is a description of the previous boot start] SH # grub will appear the following words GRUB> and then do this, if I know that my Linux is put on the first hard disk, but I don't know which partition is put on? You can enter root (HD0, then use the [Tab] key to make up, then understand. Code: GRUB> root (HD0, 8) GRUB> Setup (HD0) Please combine the article and this example, carefully I want to think about it. The partition of my first hard disk is like this ../DEV/HDA1 primary partition NTFS / DEV / HDA2 extension partition / dev / hda5 NTFS / DEV / HDA6 FAT / DEV / HDA7 FAT / DEV / HDA8 / Boot EXT3 / DEV / HDA9 / EXT3 / DEV / HDA10 / SWAP EXT3
Finally, press the [RESET] button, restart the top server side of the Windows2000 terminal service: 1. Run the regedit in the first place, find [HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETCONTROLTERMINAL ServerWDSDPWDTDS CP], see the portnumber on the right? Change it to the port number you want under decimal state, such as 7126, as long as you do not conflict with other conflicts. 2, the second hkey_local_machinesystemcurrentcontrolsetcontrolterminal serverwinstationsrdp-tcp, method is the same, remember the changed port number and the above change. Client: Open the client management connector, click a connection already entered, click File (File "→" Export (Export) ...... Use the record book or other text editing software to find the original exported This .cns file, find "Server Port = 3389" line? This default 3389 is changed to the same port number as the server. Article 11: Implementing Windows Timed Shutdown New Shortcut, Command Line Enter "Rundll32.exe User.exe, EXITWINDOWS" Select the shortcut in the scheduled task, paragraph 12: Go off the desktop icon on shortcut The small arrow wants to achieve this requirement, you must modify the registry, the method is as follows: 1). Run the Registry Editor, open the "HKEY_CASSES_ROTLNKFILE" branch. 2). Look at the LNKFile sub-key, find a key value named "IsshortCut", which means a small arrow will appear on the desktop .lnk shortcut icon. Right-click "Isshortcut", then select "Delete" from the pop-up menu, remove the key value. Then restart your loving machine, then you will see your request to reach pull. (Generally speaking, there are also some .PIF (pointing to a shortcut to MS-DOS program) Article 13: Forms in the Office document Protection Office documentation, in addition to the settings when saving And modified permissions, you can also set up the security of the form, so others can quickly plagiarize @ _ @ Method: View -> Toolbar -> Form-> Protect Forms with Copy Paste or Save As. (Or further passwords in the form: Tools -> Protection Document -> Forms) (2003.4.11 Learning the Office of the Office Skills of the Office Tips Competition CD) Article 14: Using the Uninterrupted Drainage to keep the two words in the same line In the text, the user will often encounter such a situation when entering a paragraph, and a word group consisting of multiple words (such as a name) is separated in two lines. If this is encountered, you can pass an uninterruptible space. Keep the phrase in a line of words. The method is very simple, select the space after each word (divided by the last word) and press the Ctrl Shift Space combination button.
Article 15: Win2000 Unconnected IP IP Unavailable Solution 1 Your address is also invincible, causing some friends who don't even have a friend who do not even connect to the nets. Now give a solution, but it is not guaranteed to be successful (it is unsuccessful on a large part of the NIC. :( This function of Win2000 is called "Media Sense", we can prohibit this feature through the registry: as follows: There is a keyword for disabledhcpmediansen, DWORD type under HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETSERVICESTEMCURRENTCONTROLSETSERVICESTEMCURRENTCONTROLSETSERVICESTEMCPPArameters, DWORD type (if you don't have yourself) The default is 0 that opens the detection function. It is set to 1 to turn off the probe. After the modification is completed, restart the computer. At this time, after you pull the network cable, the system does not display the network cable, but binds on the NIC IP is still tube. You can try it. I saw the post of the Fox Chong on WinMag, so I checked the Microsoft KB, and I found it, as follows: http://support.microsoft.com/default.aspx ? SCID = KB; EN-US; Q239924. Interests you can take a look .Kuka: This method I tried, it is indeed, my network card is TPLINK2918, the system is Win2000 Adv Article 16: Backup yourself Input Library Intelligent ABC Memory Word Group Save TMMR.Rem and User.Rem file in the C: \Windows \System folder, before formatting your computer, you can back up it to floppy disk or other places, format After the completion, restore it. Five input method Words Backup method: five input method phrase preserved in the c: \windows \System \WBX.EMB file, back up this file. Microsoft Pinyin input method Words Backup method: Microsoft Pinyin input The legal phrase is stored in the c: \windows \pjyyp.upt file, backed up the file. Article 17: Get real download addresses Many times we get the software download address is a steering URL, not a real address For example, this Winamp download address: http://www8.pconline.com.cn/download/download.phtml?id=96655 is a steering URL in ASP language. Sometimes you must know its address! See how I do it. Method 1: View download log with flashget Download the software. After starting the download, click "Chart / Log" below the window, click the Jet1 icon on the left, find a "redirection to" statement in the log window on the right, and the rear connection is its true address. If you don't want to download, you can use the following methods: Method 2: Using professional software --ASP2URL This is a tool software that gets the real address, you can use the class www.abc.com/down.asp?id=32 www.abc. COM / DOWN.HTML? ID = 32 www.abc.com/down.php?id=32's address translation into the real address of www.abc.com/xx.zip. Run the software, fill in the address of desired conversion, then click the "Start" button to get a real download address at the main window. Double-click to copy to the shear board, very convenient Article 18: Two NIC intercommunication network cards in different network segments (from the original Hangzhou Netcom, a friend, learning, today) method is: Get your IP as a gateway (two network cards are set this), so it is not necessarily the same network segment.
Second, MOMO said that can be used back, 1326, can you connect to deception? Specific connection method: connected to the crystal head connection network card: orange white, orange, green white, blue, blue white, green, brown white, brown, the other end does not pick up RJ-45, directly connect 13, 26, ie orange white White, orange, the other 6 lines do not use the test, this method is absolutely feasible! Article 19: NTLDR is missing solution can be inserted into the Windows 2000 CD method 1: Copy a NTLDR file, put it in C; Root Directory 2: View Boot.ini file in the console: fixmbr fixboot how to: Edit The boot.ini file in windows 2000http://support.microsoft.com/default.aspx? scid = kb; zh-cn; 311578 wonderful fault console installation new system (Figure) http://tech.tom.com/ Archive / 1380/1435/2002/12 / 4-47999.Html Article 20: Use the system's own recorder to record the sound sent by the spontaneous sound card before, today in the "Glitter Empire Essence Set 1 "I saw it and shared with everyone. This function cannot be used when serving the terminal service, because the sound of the terminal service is implemented using the RDP. Article 21: Solving document protection, prompting the solution to the disc -> Run, enter SFC / PurgeCache (note a space) Start -> Run, enter sfc / scannow (note that there is no space) if it is not, then "" Run, execute Regsvr32 appwiz.cpl, twenty-two: Retrieve the display desktop, "Show Desktop" This stuff, don't look at it, but it is a baby that improves work efficiency. It is very inconvenient to lose it. So I thought, then there will be such a situation in the future. If there is no other computer nearby, can I edit one? Use Notepad to open the "Show Desktop" file, haha, it is so simple, only a few lines in short:
[Shell] Command = 2 iconfile = Explorer.exe, 3 [taskbar] command = Toggledesktop copies this text to delete "Show Desktop".
Use Notepad to create a text file, copy this content into it, save the type as "all files", file name "Show desktop .scf", success, this icon! Then drag the icon to the toolbar, "Show Desktop" is back.
Cut carefully, the third line should be the location of the icon, change the number "3" to "4", refresh, and the icon has changed! Change it to "5", another one! Ha, this, inadvertently being discovered by I found the method of changing the "Show Desktop" icon, as long as IConfile =, enter the icon path you wish.
In fact, under the Windows9x system, if you accidentally delete the "Show Desktop", you can find the "Show Desktop" icon to type "* .scf" in the search. And under WindowsXP, you can only copy or write programs. Article 23: Modify MAC Address 1. Simple modification method is actually 98 or 2000, itself has provided the function of changing the NIC address, just that everyone doesn't think of this, so I didn't pay attention, very Simple ..... Now let's take a look at Win2000. On the online neighbor icon on the desktop, right click, select "Properties", generally have two icons in the "Network and Dial-up" window pop-up, one is a "New Connection" icon, one is "My Connection" icon . Of course, if there are two network cards on your machine, there are three icons. Now suppose you only have a network card, then right-click on the "My Connection" icon, select "Properties", and a "My Connection Properties" window will pop up. There is a "configuration" button under the window. After clicking this button, you have entered the network card's properties dialog. There are five attribute pages in this dialog, click the second "Advanced" page, and there is "Properties" Two or more, now you should see a property item called "network address", click on the item, there are two single options under the "value" identification on the right side of the dialog, the default is "do not exist" Now you only need to select a single option above, then enter the NIC MAC address you want to change in the box (note that you want to enter, don't bring "-"), such as "00E0404000A0", click "OK", OK! You have already gone! The modifications below 98 are similar to the Win2000. On the "Online Neighbor" icon, click "Properties", pop up a "Network" dialog box, in the Configuration box, double-click the NIC you want to modify, come out to a network card properties dialog. In the "Advanced" option, it is also a "network address" item under the "Properties" identity. In the two single options to the right, select the above, enter the network card MAC address you want to modify in the box, click "OK" The system will prompt you to restart. Next, I don't have to say it! :) (After restart, you can use "Winipcfg" to see the result of the modified result) If you want to restore the MAC address of the network card, just select "Nothless Display" on the right side of the "NetWork Address" to restart. Below the Win2000 is to select "Does Not exist", of course, no need to restart.
Second, the approach to the registry modified due to the relationship between the driver or NIC, there is no "network address" item in the machine, and we only modify the registry. ◆ Windows2000 modification 1, in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass {4D36E972-E325-11CE-BFC1-08002BE10318} 000, 0001, 0002 and other primary key, to find the DriverDesc, you want to change the content of description of the card, such as "Realtek RTL8029 (AS) -based PCI Ethernet Adapter. 2. Under it, add a string, named networkaddress, and its value is set to your MAC address (note address or continuously). Such as: 00E0DDE0E0E0. 3, then add a primary key called NetworkAddress in NDIPARAMS, add a string called default under this primary key, which is the MAC address you want to set, such as: 000000000000. (In fact, this is just "initial value" in the advanced attributes mentioned later, the actually used MAC address depends on the networkAddress parameters mentioned in Point 2, once this parameter is set, the advanced attribute The value is the value given by NetWorkAddress.) 4. Continue to add a string called paramdesc in the primary key of NetworkAddress, which is a description of the NetWorkAddress primary key, and its value can name itself, such as "Network Address, this will appear in the Advanced property of the NIC, is the new NetWorkAddress you just added in the registry, as long as you modify the MAC address here. Continue to add a string called OPTIONAL, and the value is set to "1", then "Does not exist" option appears when you select the NetWork Address item in the Advanced Properties of the NIC. 5, restart your computer, open the properties of the network neighbor, double-click the corresponding NIC item to find a NetWork Address's advanced settings, which can be used to directly modify the MAC address or restore the original address.
◆ Win9X modification 1, in HKEY_LOCAL_MACHINESYSTEMCURRRENTCONTROLSetServicesClasset000, 0001, 0002, etc. to find DriverDesc strings. 2, under it, add a string, name is NetworkAddress, its value is set to your MAC address, pay attention to write. Such as: 00E0DDE0E0E0. 3, then add a primary key called NetworkAddress in NDIPARAMS, add a string named default under this primary key, and its value writes the MAC address you want to set, pay attention to write, such as 00E0DDE0E0E0. 4. Continue to add a string called paramdesc, its role to specify the description of the NetTWORKAddress primary key, and its value can name yourself, such as "Network Address", so that the properties of the network neighbor will continue, so that there will be in the advanced properties of the NIC The NetWork Address option is the new NetWorkAddress you just added in the registry, and you can modify the MAC address here later. Continue to add a string named OPTIONAL, and its value is set to "1", then "no display" option appears when you select the NetWork Address item in the Advanced Properties of the NIC. ◆ Winnt's way to change the network card address: 1. Open the registry, locate the hkey_local_machine-> system-> currentControlset-> Services 2, find the key value of the NIC, add a string value networkAddress in the Parameters item, and its value is set to you The MAC address to be modified, such as "00E0DDE0E0E0". ◆ MAC address change under Linux
1. First of all, the NIC device must be closed, otherwise the system will be reported and cannot be changed. The command is: "/ sbin / ifconfig eth0 down" 2. Modify the MAC address, this step is simpler than the modification in Windows. The command is: "/ sbin / ifconfig eth0 hw ether 00 abbbccdddee" 3. Re-enable the MAC address change of the network card "/ sbin / ifconfig eth0 up" network card. Article 24: Frozen EXCEL's column (that is, not with the scroll bar) to select a row, the frozen window of the window menu will be determined. Article 25: When demonstrating the PPT, use the brush when presenting, as long as ^ P is getting, or right-click menu, pointer option, brush is OK
