The seven solutions to the Windows XP system network that cannot exchange visits

1. Check whether the Guest account is open

XP does not open the Guest account by default, so please enable the Guest account for other people to browse your computer. Also, for security, set the password or appropriate permissions for the guest. Of course, you can also set a user name and password for each machine to access each other's computers.

2. Check whether the guest user is denied access to this computer from the network

When you open the Guest account but still cannot access it at all, check to see if the settings are denying guest access to the computer from the network because XP does not allow guest to log on from the network by default, so it is not accessible even if guest is open.

When the system guest user is enabled to remove the restrictions on the Guest account, click "Start → run" and enter "GPEDIT" in the "Run" dialog box. MSC, open Group Policy Editor, select Computer Configuration →windows settings → security settings → local policies → user rights Assignment, double-click the "Deny access to this computer from the network" policy, and delete the "GUEST" account. This allows other users to access the computer using the Windows XP system over the network using the Guest account.

3. Change network access mode

XP defaults to treating all users who log on from the network on the guest account, so even if an administrator logs on from the network and only has guest privileges, try changing the network access mode if you encounter an inaccessible condition. Open Group Policy Editor, select Computer Configuration →windows settings → security → Local policies → security options, double-click the "Network access: Sharing and security mode for local accounts" policy, and change the default to "guest only-local users authenticate as guest" to " Classic: Local users authenticate as themselves.

So even if you do not open the guest, you can enter the local account and password to login to the computer you want to visit, the local account and password for the computer you want to access the account and password. If you need an account and password to access the network, you can log in by typing in the account and password already in the computer you want to access.

If you do not make changes to the access mode, you may not even enter the user name and password,//computername/guest is not available in gray. Even if the password is empty, you may not be able to click on the login without opening the guest. Change to Classic mode, at least as much as 2000 without opening the Guest account, you can enter the user name and password to log into the computer you want to enter. Perhaps you will also encounter a special situation, please see the next.

4. A noteworthy issue

We may also encounter another problem, that is, when the user's password is empty, even if you do all of the above changes are still unable to log in, Access will still be denied. This is because there is an account in the system security options: Local accounts with blank passwords only allow console logon policy is enabled by default, and users who have blank passwords are prohibited from accessing a computer that uses Windows XP over the network, based on the principle of denial of priority in Windows XP security policy. We can solve the problem by simply deactivating this policy.

In the security option, locate the "Local account with blank password only allow console login" Item, disable it, or even open guest and change to Classic mode still can not log in. After the above changes are basically accessible, you can try to choose a method that is right for you. Here are some additional questions that may be encountered.

5. Network neighbors cannot see the computer

You may not always see the computer you want to visit in your network Neighborhood unless you know the name or IP address of your computer, either by searching or directly entering//computername or//IP. Use the following action to resolve: Start the Computer Browser service. The Computer Browser service maintains a list of computer updates on the network and provides this list to the computer specified as a browser. If this service is stopped, the list is neither updated nor maintained.

137/udp--netbios name server, network basic input/output system (NetBIOS) name Server (NBNS) protocol is part of the NetBIOS (NetBT) protocol family on TCP/IP. It provides host name and address mapping methods on a network that is based on NetBIOS name access.

138/udp--netbios datagram, a NetBIOS datagram is part of the NetBIOS (NetBT) protocol family on TCP/IP for network logons and browsing.

139/tcp--netbios session Service, a NetBIOS session service that is part of the NetBIOS (NetBT) protocol family on TCP/IP for Server Message block (SMB), file sharing, and printing. Please set the firewall to open the appropriate port. It is generally possible to allow folder and Printer sharing services on the firewall only.
