Eighteen ways to clear LAN access problems

Solution to LAN access problems: The simplest solution is to restart various network devices and computers, or to turn off the network browsing server function on individual computers with the above problems.

This article introduces 18 tips for clearing LAN access problems. They are all very complicated things. For many people, this is simply confusing. Despite this, there are still many people who need to understand such a construction. The access of winXP (professional) in the LAN is a problem that often bothers everyone. Many netizens have encountered such problems. Now the author summarizes some of his personal practical experience as follows, hoping to help everyone completely solve the winXP access problem:

◆ LAN access failure Step 1: First enable the guest account;

◆In Control Panel → Administrative Tools → Local Security Policy → Local Policies → User Rights Assignment, add the guest account to "Access this computer from the network" and delete the guest account from "Deny access to this computer from the network";

◆My Computer → Tools → Folder Options → View → Uncheck "Use simple file sharing (recommended)";

◆To solve the LAN access problem, first set up a shared folder;

◆In Control Panel → Administrative Tools → Local Security Policy → Local Policies → Security Options, set "Network access: Sharing and security mode for local accounts" to "Guest only - local users authenticate as guests" (optional, this setting can remove the dialog box that requires a password when accessing, and can also be set to "Classic - local users authenticate as themselves" as appropriate);

◆Right-click "My Computer" → "Properties" → "Computer Name", and check if your LAN workgroup name appears in the tab, such as "work". Then click the "Network ID" button to start the "Network Identification Wizard": Click "Next", select "This computer is part of a business network, use it to connect to other computers at work"; click "Next", select "The company uses a network without a domain";

Click the "Next" button, then enter the workgroup name of your LAN, such as "work", click the "Next" button again, and finally click the "Finish" button to complete the settings. Generally, the above steps can basically solve the problem. If it doesn't work, read on:

◆ Check if the local connection is disabled, right-click "Local Connection" → "Enable";

◆To solve the LAN access problem, the network firewall must be turned off;

◆ Check if the domain is enabled, if it is joined to the domain and check the domain settings;

◆Check whether the server service is closed;

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

◆ "Local Area Connection" → Properties → General, check whether "File and Printer Sharing for Microsoft Networks", "Client for Microsoft Networks" and TCP/IP protocol are installed;

◆Some LAN games and software require the installation of NetBEUI protocol. And there are articles online saying that in small LANs, the TCP/IP protocol and NWLink IPX/SPX/NetBIOS compatible protocol supported by Microsoft in WinXP do not perform well. In small LANs (networks with about 200 computers), NetBEUI is the protocol that takes up the least memory and is the fastest.

Installation method to solve LAN access problems: ① Insert the Windows XP installation CD, go to the "valueaddMsft et etbeui" directory and copy Netnbf.inf to C:WindowsINF; ② Copy Nbf.sys to C:WindowsSystem32Drivers; ③ Start → Control Panel → "My Network Places" → "Network Connections" → "Local Area Connection" (the LAN connection you are currently using), right-click → "Properties" → "General" → "Installation" → "Communication Protocol" → → "Add", then you can see the "NetBEUI Protocol" item (this item was not originally available), select NetBEUI, and press OK.

◆The computer used as the network browsing server cannot update the computer list on the network due to viruses, low configuration, slow operation, or freezing, so that some machines cannot be found in the network neighborhood sometimes. Solution: The simplest way is to restart various network devices and computers, or turn off the network browsing server function on individual computers with the above problems. The method is as follows:

Disable Computer Browser service in Windows 2000/XP

◆Patch the system. WinXP has a slow access to My Network Places. This is a bug in WinXP. When we open My Network Places, the operating system will first search for it from the scheduled tasks, which greatly affects the access speed. This problem will not exist unless you have installed the SP1 patch.

You can manually resolve this problem. Find the "HKEY_LOCAL_MACHINE

SOFTWAREMicrosoftWindowsCurrentVersionExplorerRemoteComputerNameSpace", there is a subkey named "", which points to "Scheduled Tasks", just delete it directly.

◆Solve LAN access failure: first uninstall the network card driver, restart and then reinstall;

◆Hardware problem: check the network card, network cable, hub, router, etc. Before checking, it is best to restart the network equipment (hub, switch, router) to see if the problem can be solved;

◆ Virus (Trojan) reasons: Upgrade the virus database and perform a full disk scan in safe mode.
