When XP is used for the first time, you will have a new network connection to the network installation wizard in the properties of the online neighbor.
1. Check the physical connection between the computer.
The NIC is the basic device of the network connection. In the desktop computer, the indicator behind each NIC should be bright, which means the connection is normal. If it is not bright, check the hub or switch is open, and the indicator of each client connection is bright, which means the link is normal. Next, check whether the crystal head of the network cable is in good contact.
2, make sure TCP / IP is installed on all computers, and work is normal.
TCP / IP is installed by default in Windows XP. However, if you want to uninstall the network problem, you will not be easy: This connection displayed in the Local Connections Properties Use the Internet Protocol (TCP / IP) item using the list of items, you will find Unloading buttons are not available (disabled). This is because the Transmission Control Protocol / Internet Protocol (TCP / IP) stack is the core component of Microsoft XP / 2003 and cannot be removed. In this case, if you need to reinstall the TCP / IP to restore the TCP / IP stack to the original state. You can reset the TCP / IP stack using the NetShell utility to restore the status of the initially installed operating system. The method is: Type the following command after the command prompt, then press ENTSH IP RESET C: /RESETLOG.TXT, where the resetLog.txt records the log files of the command result, must specify, specified RESETLOG.TXT Log files and complete paths. The results of running this command are the same as deleting and reinstalling the TCP / IP protocol.
3. Use the ping command to test the connection between two computers in the network:
PING Other Computer IP, in the command prompt, type ping x.x.x.x (where X.x.x.x is another computer IP address), then press ENTER. You should be able to see several answers from another computer, such as:
Reply from x.x.x.x: bytes = 32 TIME <1MS TTL = 128
If you don't see these replies, or see "Request Timed Out", you may have problems with local computers. If the ping command is executed successfully, then you determine that the computer can connect properly and skip the next step. If you don't see these replies, or see "Request Timed Out", you may have problems with local computers. PING Local IP, if you see "Request Timed Out", you may have problems with local computers.
4. Use the ping command to test whether the name resolution in the network is normal
Ping computername, where computername is the name of the remote computer. Test your computer with the name of the ping command. Method for determining the name of your computer is: Enter SystemInfo at the command prompt. Or right-click on my computer-property on your desktop, and then click the Computer Name tab. If you see the success of the command, you have basic connection and name resolution between your computer. Name resolution is closely related to NetBIOS, look at the following steps.
5, correctly install network components
First click on the online neighbor-property, select the network card to share. Set IP on the same network segment of the LAN. For example, 192.168.1.x network segment. Then look at the advanced properties of TCP / IP, do NetBIOS.
In a network system built using Winnt 4.0, the unique identification information for each host is its NetBIOS name, the system uses WINS services, information broadcasting methods, and LMHOST files, etc., the NetBIOS name is parsed to the corresponding IP address. Thereby information communication.
In the internal network system (that is, usually in the local area network), it is very convenient and fast to use the NetBIOS name. However, in the Internet, the unique identification information for a host is the domain name (163.com) in its FQDN format. In the Internet, the DNS standard is used to realize the domain name to the corresponding IP address, Win2K support Dynamic DNS, run Active Directory Service The machine can dynamically update the DNS table. WIN2K networks can no longer need WINS services, but Win2k still supports WINS, which is due to backward compatibility. At present, most networks are mixed nets, both Win98 and other systems, and WinXP / Win2K and other systems, therefore need to bundle NetBIOS parsing computer name on the TCP / IP protocol.
Check if "File and Print Service" component is selected, if you have selected it, "Browse Service" will not be bound to the NetBIOS interface. By backing up the browser and does not enable "File and Print Sharing", Windows-based computer cannot share the browsing list with the client. Any computer that will include the computer in the browse list must also enable "File and Print Sharing".
6. Enable print and file sharing.
You can see if the printer and file sharing are installed in the online neighbor and local connection properties. Verification: If you can't see your own machine in the neighbors, you don't have a printer and file sharing.
7, start "computer browser" service
Computer Browser Services Maintain a list of computers on the network and provide this list to a computer specified as a browser. If you stop this service, you neither update or maintain the list.
Win2K / XP To make sure the computer browsing service is started normally. Turn on Computer Management -> Services and Applications -> Services, make sure "Computer Browser" is not stopped or disabled in the right window.
8, run the network identity wizard
My computer selects "Properties", and then click the "Computer Name" tab to click the Network ID button, start the Network Identity Wizard: Click Next, Select "The unit is part of the business network, It connects to other working computers "; click" Next ", select" The company uses no domain network "; click the" Next "button, then enter your LAN's workgroup name, click" One step button, finally click the "Finish" button to complete the setting.
9, Win2K installation NetBeui protocol
The NetBeui protocol in Win2k is an efficient protocol to make this protocol:
Online Neighbor -> Properties -> Local Connection -> Properties ----> Installation ------> Agreement -------> NetBeui Protocol
10, start with Guest (guest) account
Windows XP's guest account allows others to use your computer, but they don't allow them to access specific files or they are not allowed to install software. All network accesss to Windows XP Professional Computers in a Windows XP Home Edition computer or Working group use guest accounts. Using NET User Guest to ensure that the guest account is set for the network, if the account is active, a line is similar to the following: Account Active Yes; if the account is not an active, please use the following command to grant a guest Account Network Access:
NET User Guest / Active: YES
Or open the control panel -> User account or open guest accounts in the management tool -> Computer Management -> Local users and groups
11. Allow guest accounts to access from the network.
Enter gpedit.msc, pop-up policy manager, pop-up policy manager, in 'computer configuration -Windows Settings - Local Policy - User Rights Assign', "Rejecting this computer" policy to prevent this computer from the network, If there is a guest account, the solution is to delete the Guest account in the denial of access. 12, firewall:
Make sure that WinXP's own firewall is not turned on, open your local connection properties -> Advanced, turn off the Internet Connection Firewall. If a third-party firewall product is used, refer to its manual to ensure that the firewall does not disable communication with the following ports: UDP-137, UDP-138, TCP-139, TCP-445 (Win2K and later operating systems).
Windows XP latest SP2 patch has made great improvements to ICF, more powerful, ICF has its own setup item, after installing SP2, by default, enable ICF firewall, do not allow any external active connection, even local Applications To access the network, you also need to make settings in your license list.
However, the firewall blocks normal network browsing service communication, the result is that others can't see your computer in the online neighbors, there is no two full beauty ways to allow browsing services under the premise of opening firewalls.
The way is that if ICF is turned on, open the property, in the service bar, select Add, add the service dialog box, and the first is the first description service name, so that the memory, from top to the next is the application The IP address or name of the service is input 127.0.0.1 represents the unit.
The following is an inside and outside port number, and the TCP / UDP sign next to it is a UDP connection or a TCP connection.
Enter 3 services according to the table below
Name protocol port
NetBIOS Name Service UDP 137
NetBIOS DataGram Service UDP 138
NetBIOS Session Service TCP 139
137 / UDP - NetBIOS Name Server, Network Basic Input / Output System (NetBIOS) Name Server (NBNS) protocol is part of the NetBIOS (NetBT) protocol on TCP / IP, providing hosts on networks based on NetBIOS name Name and address mapping method.
138 / UDP - NetBIOS Datasheet, NetBIOS Datasheet is part of the NetBIOS (NetBT) protocol on TCP / IP, which is used for web login and browsing.
139 / TCP - NetBIOS session service, NetBIOS session service is part of the NetBIOS (NetBT) protocol family on TCP / IP, which is used for server message block (SMB), file sharing and printing.
13. Check the RPC, the PLUG AND PLAY service has started, check the permissions of the corresponding system folder, re-register the following dynamic link library:
Regsvr32 netshell.dll
Regsvr32 netcfgx.dll
Regsvr32 Netman.dll
14, set account and password
Due to the operating system of the Winnt kernel, when accessing the remote computer, it seems to be trying to try with the local current username and password. It may cause unacceptable, where the user password is added here.
15, multiple ways access "network computer"
For example, to open a computer named "killer" in the network, its IP address is 192.168.1.8, if you don't know the IP address of other machines, you can use "Ping Computer Name" to get its IP address.
Use computer name access to NetBIOS. Click the "Start" menu, click Run, enter "/ killer" in the address bar, click OK. Use IP address to enter "/192.168.1.8" in the address input field, click OK.
Access to methods of searching, computer update lists require time, search computers can speed up the list of updates. Click "Search Computer" in "Online Neighbors", enter the computer name, click "Search Now", you can see the computer you want to access. Double-click on the right computer name to open it.
Access to the Map Drive, enter the DOS mode, enter "NET View / Killer", Enter the Enterprise to see which shared folders on the computer Killer, such as D. Enter NET USE Z: / killer / D Map the folder D shared by the computer IBM-ZB to the H: disk, type "Z:" at the command prompt. You will find that you have already connected to the Killer computer.
