Solutions for xp lan Settings and XP inability to access LAN

I believe that many people have the same experience as I have. All the settings of the network composed of Win XP are exactly the same as those of Win 2000, but there is still a situation that cannot be accessed at all, I think this is mainly because the security settings of XP are different from those of 2000. In response to this problem, I checked some information on the Internet and tested the common solutions provided on the Internet. Now I will introduce them to you, I hope this will be helpful to the netizens who have encountered this problem. Part of the content is taken from the Internet. Please forgive me for not specifying the source one by one.

First, we will only talk about policy issues, instead of physical connections and other issues. In addition, please install the corresponding protocol and set the correct IP address, and try to set the computer in a working group with the same IP address segment.

Second, there are many descriptions of problems on the Internet, so I will not describe them here. When there is a problem with sharing and access, consider the following steps: 1. Check whether the Guest account is enabled

XP does not enable the Guest account by default, so enable the Guest account for others to browse your computer. To ensure security, set a password or corresponding permissions for guest. Of course, you can also set a user name and password for each machine for mutual access between computers.

2. Check whether the Guest user is denied access to the local machine from the network

When you enable the Guest account but still cannot access it at all, check whether it is set to deny access to the computer from the guest network, because XP does not allow access from the network by default, therefore, even if guest is enabled, it cannot be accessed. When the system Guest user is enabled, remove the restrictions on the Guest account. Click "Start> Run" and enter "gpedit" in the "run" dialog box. MSC, open the Group Policy Editor, select Computer Configuration> Windows Settings> Security Settings> Local Policy> User Rights Assignment, and double-click the Deny access to this computer from the network policy, delete the "guest" account. In this way, other users can use the Guest account to access computers using Windows XP through the network.

3. Change the Network Access Mode

XP processes all users logged on from the network according to the Guest account by default. Therefore, even if the Administrator logs on from the network, the Administrator only has the guest permission, try to change the network access mode. Open the Group Policy Editor, select "Computer Configuration> Windows Settings> Security Settings> Local Policies> Security Options", and double-click the "Network Access: sharing and security modes of Local Accounts" policy, change "guest-Local User-initiated identity verification" to "classic: Local User Authentication" by default ".

In this way, even if you do not enable Guest, you can enter your local account and password to log on to the computer you want to access, the local account and password are your accounts and passwords in the computer you want to access. If you need an account and password to access the network, you can log on by entering the account and password in the computer you want to access.

If you do not change the access mode, you may not be able to enter the user name and password, // computername/guest is unavailable. Even if the password is empty, you cannot click confirm to log on without enabling guest. In Classic mode, you can enter the user name and password to log on to the computer, just as in the case that the Guest account is not enabled in section 2000. You may also encounter a special situation. Please refer to the following section.

4. A noteworthy question

We may also encounter another problem, that is, when the user's password is empty, the access will be rejected even if you have made all the above changes and still cannot log on. This is because the policy "Account: A local account with a blank password can only log on to the console" in the system "Security Options" is enabled by default, according to the Denial-of-priority principle in Windows XP security policy, users with blank passwords are prohibited from accessing Windows XP computers over the network. We only need to disable this policy to solve the problem. In the security options, find the "allow console logon only for local accounts with blank passwords" option and disable it. Otherwise, you cannot log on even if you have enabled guest and changed it to the classic mode. After the above changes, you can access them. You can try to select a method that suits you. Next we will add some other problems that may occur.

5. network neighbors may not be able to see the computer you want to access in network neighbors, unless you know the computer name or IP address, by searching or directly entering // computername or // ip. Follow these steps to start the "Computer Browser" service. "Computer Browser Service" maintains a computer update list on the network and provides this list to the computer designated as the browser. If the service is stopped, the list is neither updated nor maintained.

137/udp -- NetBIOS name server. The NetBIOS Name Server (NBNS) protocol is part of the NetBIOS (netbt) protocol family on TCP/IP, it provides the Host Name and Address ing method on the network accessed Based on NetBIOS name.

138/udp -- NetBIOS datagram. NetBIOS datagram is part of the NetBIOS (netbt) protocol family on TCP/IP. It is used for network login and browsing.

139/tcp -- NetBIOS session service. NetBIOS session service is part of the NetBIOS (netbt) protocol family on TCP/IP. It is used for Server Message Block (SMB), file sharing, and printing. Set the firewall to enable the corresponding port. Generally, you only need to allow the folder and printer sharing service in the firewall.

6. About the Sharing Mode

By default, shared XP only grants the guest permission or allows users to change "my files ". In Windows 2000, you can easily set the shared attributes of a folder. You only need to right-click the folder and select Properties to view the shared settings tag. In Windows XP, folder sharing is complicated, and users cannot see the sharing setting label through the above operations. The specific modification method is as follows: Open "Tools" in "My Computer", select "folder properties", and bring up the "View" tag, scroll to the bottom of the "Advanced Settings" section to cancel the selection before "simple file sharing (recommended, in addition, if the option bar contains the "Mickey Mouse" item, you can also cancel it. In this way, you can easily modify the folder attributes like Windows 2000.

7. Questions about inresponsiveness or slow response to access by network neighbors

When browsing network neighbors in WINXP and win2000, the system will be delayed by 30 seconds by default. Windows will use this time to search for specific scheduled tasks on the remote computer (or even to search the Internet ). If the network does not respond during the search, there will be an unlimited wait, so it is not surprising that the latency of more than 10 minutes or even an error is reported. The specific solution is as follows. A. Disable the scheduled Task Service (Task sched) of WINXP)

You can go to "control panel, administrative tools, and services" to open the "Task Scheduler" attribute dialog box, click "stop" to stop the service, and set the start type to "Manual ", in this way, the service will not be automatically started at the next startup. B. Delete two subkeys in the registry.

Go to the Registry and find the master key "hkey_local_machinesoftwaremicrosoftwindowscurrentversionpolicerremotecomputernamespace" to delete the following two child keys.

Among them, the first child Jian decides whether to search for online printers (or even search for printers on the internet). If there is no shared printer on the network, the key can be deleted. The second child Jian decides whether to search for the specified scheduled task, which is the culprit of slow network neighbors and must be deleted.

Summary

Inaccessible mainly because XP does not enable Guest by default, and even if guest is enabled, XP does not allow guest to access the computer from the network by default. There is also a noteworthy problem. I believe that some places that do not consider security or computer companies give people blank system passwords, but this is not allowed to log on. If you have tried the above methods, I believe there will be no more problems.
