18 solutions to LAN access failures in XP Professional Edition

Recently, I have frequently asked questions about WINXP access in the LAN. My personal experience is summarized as follows:

1. Enable the guest Guest account;

2. Control Panel → Administrative Tools → local security policies → Local Policies → user rights assignment, add a guest account to "access the computer from the network, and "Deny access to this computer from the network" to delete the Guest account;

3. My computer → tools → Folder Options → view → remove the check box before "using simple file sharing (recommended;

4. Set shared folders;

5. Choose "Control Panel"> "Administrative Tools"> "Local Security Policy"> "Local Policy"> "Security Options" and set "network access: the sharing and security mode of the local account is set to "Guest only-Identity Authentication for guests from the local user" (Optional). This setting removes the dialog box requiring a password for access, it can also be set to "classic-Local User Authentication ");

6. Right-click "my computer"> "properties"> "computer name". Does the tab show the name of your LAN Workgroup, such as "work. Click the "Network ID" button to start the "Network ID wizard": click "Next" and select "the local machine is part of the commercial network and connected to other working computers "; click "Next", select "company uses networks without domains", click "Next", and enter the name of the Working Group of your LAN, such as "work ", click "Next" again, and then click "finish" to complete the settings.

Generally, the above steps can be solved. If not, read the following link:

7. Check whether the local connection is disabled. Right-click "Local Connection"> "enable ";

8. Disable the network firewall;

9. Check whether the domain is enabled, whether the domain is added, and whether the domain settings are checked;

10. Check whether the server service is disabled;

11. Check whether the local connection IP address, subnet mask, gateway, and DNS settings are correct;

12. "Local Connection" → properties → General, check whether "Microsoft network file and printer sharing", "Microsoft network client", and TCP/IP protocol are installed;

13. netbeui protocol must be installed for some LAN games and software. And there areArticleIn a small LAN, Microsoft only supports TCP/IP protocol and nwlink IPX/SPX/NetBIOS protocol in WINXP, which are not satisfactory, in a small LAN (with a network of around 200 computers), netbeui is the protocol with the lowest memory usage and the fastest speed.
Installation Method:
& #9312; on the Windows XP installation disc, go to the "valueaddmsft et etbeui" directory and copy netnbf. inf to c: \ windows \ INF;
& #9313; copy NBF. sys to c: \ windows \ system32 \ drivers;
& #9314; → Control Panel → network neighbor "→" network connection "→" Local Connection "(that is, your current LAN connection) right-click, select "properties", click "General", click "Install", click "Communication Protocol", and click "add ", in this case, you can see the "netbeui protocol" item (this item was not available in the past). After selecting netbeui, press OK.

Solution: the simplest method is to restart various network devices and computers, or disable the network browsing server function on some computers with the above problems. The method is as follows:

15. patch the system. The access speed of WINXP to the network neighbor is slow. This is a bug in WINXP. when we open the network neighbor, the operating system first searches for the task, which greatly affects the access speed, this problem does not occur unless you have installed the SP1 Patch.
This problem can be solved manually. Find "\ HKEY_LOCAL_MACHINE \" in the registry \
SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ remotecomputer \ namespace, with a subkey named {D6277990-4C6A-11CF-8D87-00AA0060F5BF} pointing to the scheduled task (scheduled tasks) ", delete it directly.

16. Uninstall the NIC Driver, restart and reinstall the driver;
