I searched this on the internet and practiced it myself. I hope I can help you. Seven solutions (1) to the problem of mutual access between WinXP system and network, I believe many people have the same experience as the author. "All the settings of the network composed of WIN XP are exactly the same as those of WIN 2000", but there are still cases where it is completely inaccessible. "I think this is mainly because the security settings of XP are different from those of 2000." In view of this problem, I looked up some information on the Internet "and tested various common solutions provided on the Internet." Now I want to sort it out and introduce it to you. The netizen who came here to ask questions is helpful. Please ask the experts to continue to point out that some of the contents are taken from the network. Please forgive me for not indicating the source one by one. First of all, we don't consider physical connection and other issues here. We only talk about policy issues. In addition, please install the corresponding protocol and set the IP address correctly. Try to set the computer in a working group and have the IP address of the same network segment. Secondly, there are many descriptions of the problems on the Internet, so I won't go into details here. When there is a problem with access, please consider the following steps: 1. Check if the guest account is open. By default, XP does not open guest accounts. Therefore, in order to let others browse your computer, please open the guest account. At the same time, for the sake of safety, please set a password or corresponding permissions for the guests. Of course, you can also set a user name and password for each machine to facilitate mutual access between computers. 2. Check whether the guest user is denied access to the computer from the network. When you open a guest account, you still cannot access it. Please check whether the settings deny guests access to the computer from the network. Because XP does not allow guest to log in from the network by default, even if they are turned on, they cannot access it. When the guest user of the system is turned on, the restrictions on the guest account are lifted. Click Start → Run. Enter GPEDIT. MSC ""In the running dialog box, open the Group Policy Editor, then select Computer Configuration →Windows Settings → Security Settings → Local Policy → User Permission Assignment, and double-click the policy of "Denying access to this computer from the network" to delete the "Guest" account, so that other users can use the GUEST account to access computers using Windows XP system through the network. By default, network access mode XP treats all users who log in from the network as guest accounts. Therefore, even if the administrator logs in from the network, he only has the permission of the guest. "If you can't access it, please try to change the access mode of the network. Open the Group Policy Editor and select Computer Configuration →Windows Settings → Security Settings → Local Policy → Security Options. Double-click the network access of the local account: *. The "Enjoy and Safe Mode" policy changes the default setting of "Guest only-local users authenticate as guests" to "Classic: local users authenticate themselves", so that you can log in to the computer you want to access by entering the local account and password "Local account and password are the existing accounts and passwords in the computer you want to access" and by entering the calculation you want to access "If you want to access the network, you need an account and password". If you don't change the access mode, "You may not even be able to enter the user name and password" //computername/ Guest is grayed out and unavailable. Even if the password is empty, you can't click OK to log in. Switch to classic mode. At least, you can log in to the computer you want to enter by entering your user name and password. Maybe you will encounter special circumstances. Please see the following seven solutions to the problem that the network of WinXP system cannot visit each other (2). A noteworthy problem is that we may encounter another problem, that is, when the user password is empty, even if you make all the above changes, you can't log in. Access will still be denied. This is because the policy of "Account: Only local accounts with blank passwords are allowed to log on to the console" is enabled by default. According to the principle of denial priority in Windows XP security policy, the password is blank. When users access computers using Windows XP through the network, they will be banned. We can solve this problem by canceling this policy. In the security option, we can find the item "Only allow local accounts with blank passwords to log in to the console". Otherwise, even if we open the visitor and switch to classic mode, we still can't log in. After the above changes, we can basically visit. You can try to choose a method that suits you. The following is a supplement. Fill in other possible problems. 5. Network neighbors can't see the computer. By searching or directly typing //computername or//you may often not see the computer you want to visit in your online neighborhood "unless you know the name or IP address of the computer". Please solve the IP problem as follows: start the computer browser service, maintain a computer update list on the network, and provide this list to the computer designated as the browser. If this service is stopped, the list will not be updated or maintained. 137/UDP-NetBIOS name server "NetBIOS basic input/output system". Name Server (NBNS) protocol is a part of NetBIOS(NetBT) protocol family over TCP/IP. "It provides host name and address mapping method 138/UDP-NetBIOS datagram" NetBIOS datagram is NetBIOS over TCP/IP. Part of the protocol family "It is used for network login and browsing 139/TCP-NetBIOS session service" NetBIOS session service is a part of NetBIOS(NetBT) protocol family on TCP/IP "It is used for server message block (SMB) file sharing and printing" Please set the firewall to open the corresponding port ". 6. About * * * Enjoy mode * * Enjoy XP. By default, only visitors are given permission or users are allowed to change "My File". In the Windows 2000 operating system, it is easy for users to set the * * * enjoy attribute of a folder. Just right-click the folder and select Properties to see the * * * Enjoy Settings tab, and set the folder in the Windows XP system. Enjoying time is more complicated. " Through the above operations, users can't see the * * * enjoyment setting tab. "The specific modification method is as follows: open the tools in my computer, select folder properties, bring up the view tab, and scroll to the bottom in the advanced settings section to enjoy simple files (recommended). In addition, if the option bar has "Mickey Mouse", deselect it. After modification, users can modify the folder properties as easily as using Windows 2000. WinXP system network cannot exchange visits. Seven solutions (3) 7. Regarding the problem of no response or slow response when visiting network neighbors in WinXP and Win2000, the system will delay for 30 seconds by default. " "Windows will use this time to search whether the remote computer has a specified scheduled task (or even search on the Internet)." If the network does not respond when searching, it will fall into infinite waiting. "Then it is not surprising to report a delay of more than 65,438+00 minutes or even an error. The following are specific solutions. Sk scheduler can go to Control Panel/Administrative Tools/Services, open the properties dialog box of Task Scheduler, click Stop to stop the service, and then set the startup type to Manual, so that the service will not be started automatically next time. B. Delete two subkeys in the registry, find the primary key in the registry, and delete the following two subkeys: and "The first subkey determines whether online neighbors should search for printers on the Internet (even). Rnet) "If there is no printer in the network, you can delete this key." The second subkey determines whether the specified scheduled task needs to be found. "This is the chief culprit of the slow neighbors of online games." The subitem must be deleted. 9. Close the firewall to sum up, mainly because XP does not open visitors by default. Even if the guest is turned on, by default, XP does not allow the guest to access the computer from the network. I believe that the system password given by some places or computer companies that do not consider security is empty, but this is not allowed to log in. As long as you try the above method, I believe there will be no more problems.
