Online neighbors can't find a server
Q: The unit network has been using normal, but it is open for a certain morning, most of the computer can not get online (computer prompt communication failed), can't find the server from the network neighbor. Repeating did not find any viruses. It is thought that the part of the switch is broken, so that the port of the machine that cannot be networked is changed to the exchange port used by the machine that can be online, it is still not. How is this going?
A: From the above situation, it is estimated that there is a virus such as "shock wave" on your network. I can't find a virus. It is recommended to close the switch to check each computer in your network. In addition, check the status indicator on the switch before turning off the switch, if the indicator has been "guilty", indicating that the network load is relatively heavy, is a typical manifestation of the "shock wave" virus. Please check each computer in the network with the latest anti-virus software and install the impact wave patch of the Windows 2000 / XP system. After the problem of excluding the virus, please refer to the "Computer Daily" 2004 "Neighborhood Isn't difficult to - Perspective Online Neighborhood" to set up online neighbors.
Computers can only access the provincial site
Q: My unit has a local area network. When using ADSL, the dial-up host and Win98 operating system can access all websites, while other WinXP systems can only access the website in the province, please give a guidance.
A: The machine of the WinXP system can access the site, explain the gateway, DNS and other settings, the problem may appear in the proxy server, you can try to try with other proxy software sharing, or directly enable the route function of ADSL MODEM .
OE has a 505 error
Q: Collect mail with Outlook Express, recently found only to collect mail, can not send an email. Every time you send a new email: "Since the server refuses to accept the sender's email address, this email cannot be sent. The sender's email address is" xxxx@tom.com ". Theme 'Ghuuu' Account 'pop.tom.com' server ' smtp.tom.com' protocol SMTP server response '505 error Client Was Not Authenticated' port 25 Safety ssl Server error 505 error number 0x800ccc78 ". What is the problem? How to solve it?
A: This problem occurs, mainly in your OE account settings, in the Server tab, do not select "My Server Requirements Authentication" under the "Out of Mail Server" (505 Error Proof Server There is no user verification through your account). Please configure OE help information when you provide you with the OE transceiver. Typically, select the "The same settings as the received mail server" option.
Diskless network sharing Internet access
Q: My school is used by the Winnt system server, with the online famous "Shandong Zhang Yuti" version of the free diskless Win98 software installed the RPL diskless network. Now our school has access to ADSL, you want to share 25 student machines, how should we set up? Teacher's dormitory and school rooms exceed 100 meters, if you also access the ADSL host, you can do it in the host Insert another BNC network card (all of the school use of the RJ45 connector), with a coaxial cable (without HUB) and school host network? Is there any other more economical solution?
A: From your question, your ADSL line has access to a host and use this host to make a proxy server. According to the different agent software you have, do the following settings on your diskless station: If It is the use of the NAT class software, your diskless station needs to set the gateway and DNS. The address of the gateway is the IP address of the proxy server, and DNS is the address provided by local telecommunications. But because you are using the "Shandong Zhang Yuti" version of the free power, the gateway of the free disk workstation, the DNS should set together when installing. If there is no settings when installing, you can only re-use the RPL disk, and set it according to the instructions in diskless software.
If you use a pure agent class software, it is necessary to set the proxy server address in IE, it is relatively simple, you only need to set a proxy server in the IE of each diskless station.
For the second question, if your home is not more than 185 meters, you can use 1 strainer directly. If more than 185 meters, it is best to connect with a coarse cable.
Usually, there are 16 ports of HUBs with cables or coarse cables, and they can directly connect the thin cable or thick cable to the HUB, without having to insert a BNC interface network card, directly install a BNC interface directly on your computer. The network card is OK, the TCP / IP related settings of your machine should be the same as the 25-free settings of the school.
Dial Server Tips 691 Error
Q: Use the neighbor's Windows 98 system machine to make a dial server, my Windows XP machine dial, always connect, prompt "User name, password can not be used in this domain 691", two machines in the same group, What is going on in the computer name?
A: This is why you are not set in the dial-up server in Windows 98. When the Windows XP system dials to the Windows 98 server, you need to use the password set by the Windows 98 server. The settings on Windows 98 are as follows:
Click Dial Network from "Start → Programs → Accessories → Communication", in the Dial Network window, click Connects menu, select Dial Network Server, in the "Dial Server" pop-up, Select "Allow Dial" and click the "Change Password" button. In the pop-up "Dial Network Password" dialog box, set the password in "New Password" and "Confirm the New Password", such as 1234. Then click the "OK" button twice.
When the Windows XP system is connected to Windows 98 via a dial-up network, the phone number inputs the phone number of the Windows 98, and the username is free to enter, the password is the password set in the "Dial Server" just in Windows 98. Finally, click the "Connection" button.
DHCP error causes system abnormal restart
Q: Recently, my Windows XP system suddenly restarted in the running process and the reporting system recovered from major errors. Then everything is working properly. This phenomenon occasionally occasionally.
Error report is "C: windowsminidumpmini010104-01.dmp
C: Docume ... OwnerLocals ... Tempwer1.temp.diroosysdata.xml. "Nothing to use KV2003 anti-virus and online tapping.
Every run is a warning on the System Event Viewer Source: DHCP Description is: The computer has automatically configured the IP address of the network card of 000795d3eoed. The IP address used is 169.254.185.9, "What is the reason?
A: When the IP address is set to 169.254.x.x, it means that the address cannot be obtained.
From your situation, it is estimated that the system file is corrupted, please insert the CD of the installation system in the CD-ROM drive, run SFC / ScanNow to check the repair system file.
Log in to the route interface to access the Internet
Q: Use an ADSL broadband to access the Internet, add a router to make two computers online. PPPoE dial is set on the router. I have been working properly, but I have recently been out: I can't access the Internet after the computer is turned on. I must use the browser to open the login interface of the router (do not need to log in), then the network is passed. IP address settings have no problem, ADSL Modem is the ZTE ZXDSL831 Router is SMC7004ABR, and the two computers have installed Windows XP and Windows 2003, respectively. What is the reason? In addition, the "Computer News" of 2003, "Computer News" once mentioned how ZTE ZXDSL831 sets the PPPoE Internet access, but opened the setting interface, found completely different, set it, reboot MODEM Dial-up Internet access, but you can't get online information, I hope to be able to advice.
A: If you just have two computers in your home, when you don't use a broadband, turn off the ADSL MODEM and routers. When you use, turn on the ADSL and routers and computers, which should not appear.
In addition, it can be seen from the ZTE website that ZXDSL831 is a routing function, so it can save the next router. As for the detailed setting method, you can view it on http://www.zte.com.cn/service/service5.asp.
How to solve the network
Q: Use ADSL in the WinXP system to use ADSL mode, just when you just access the network. Recently, after the startup system enters the desktop, the dialog box prompts "Windows - System error, and the network" are renowned. How to solve it? In addition, after winning the cuteftp software in the WinXP system, each time the browser will automatically turn off and the dialog prompt "Explore.exe is about to close", how to solve it?
A: For the first question, the solution is to modify the name of your computer: Right-click My Computer, select "Properties" from the pop-up menu, click Computer Name tab, single Click the "Change" button and re-enter a name in the "Computer Name" in the pop-up dialog box, click the "OK" button to change.
The second question may be that your CUTEFTP version is conflict with the system. Please try to install additional version of Cumeft or other FTP client software such as FlashFXP.
The startup speed is too slow in the network.
Q: I originally used Windows 2000. After booting into the desktop, I always paused for 1 minute, and there is no program, including firewalls and MSN, etc.. Reinstall the system, or changed to a Windows XP system, it can have this problem in a period of time, but this issue will always have. But there is no such problem without unplugging the network cable. And when the system is turned on, it seems to always do network certification. What is the reason?
A: Most of the Windows system is used to reinstall, especially after frequent installation software or use a longer period of time. There are more and more programs installed in the system, the slower starting, which is normal. But after unplugging the network cable, start the start, it may be the following reason:
1. Your computer is in the local area network and joined the Windows2000 ActiveDirectory (Active Directory), after logging in to the network, you need to authenticate or other network operations, this takes time. When unplugging the network cable, Windows 2000 does not detect the network, and will not perform corresponding network operations, speed is fast.
2. Another reason may be caused by a virus. Many malicious code viruses, automatically open some networks or log in to the specified website when the system is started, which will also cause slower speed. Online neighbors can not use machine name access
Q: When the computer reloaded in the network is in the online neighbor, it is input / computer name, such as / 20, and the speed is very fast. You can have a computer in the operation input / 20 can not find the machine (failure) The machine uses Me Ping VOD on-demand system), and the client speed is very slow, sometimes I can't enter. what is the reason?
A: 1. The name of the computer, it is best to start with letters because simple numbers often be parsed by parsed IP addresses.
2. This happens after reinstalling the system, it should be that the NIC driver or network protocol is not installed. Please enter the security mode, delete the NIC driver, and delete other network cards (if any) drivers and "Dial-up Network Adapters", restart and reinstall the network card driver and related protocols.
3. In a network, if the number of computers in the same network segment is more, there will be a short pause when using the "/ computer name", which is normal.
Router refused service
Q: After logging in to the router, the following prompt "Denial of Service Attack from 61.149.185.54 is finished", "Denial of Service Attack from 218.80.104.168 is underway", and continuous display, what is going on?
A: This should be your router settings that do not allow you to log in from the WAN. You can log in to the local domain port of the router for setting (192.168.x.x, 10.x.x.x, 172.16.x.x).
Switch port idle is not necessary
Q: Can a 24-port switch can connect to PC? Or must there be 1 or 2 ports to be idle? If you must be free, do you usually have a few ports (UPLINK port)?
A: The common 24-port switches can be connected to the PC, which can be used with 24 ports. Although there is a 24-port switch with 25 ports, the 5th port is the same, but the port of the port is different.
