Because Windows XP constitutes the operating system network settings and Windows 2000 exactly the same, but there is still no access at all, I think this is mainly because XP security settings and 2000 are not the same. In response to this problem, the author checked some information on the Internet and tested various common solutions provided online. Now I will introduce it to everyone, I hope that I can help the users who have encountered this problem, and please continue to give pointers to the experts. .
First of all, there is no physical connection and consider other issues, and talk about strategic issues. In addition, please install the corresponding protocol and set the IP address correctly, and try to set the computer in a working group and have the IP address of the same network segment.
Secondly, the online description of the problem for many, there is no longer tired. When sharing and access problems, please consider the following steps:.
1 guest checking account is turned
XP does not open the guest account by default, so some order Others can browse your computer, please enable the guest account. At the same time, for security, please set a password or corresponding permission for the guest. Of course, you can also set a username and password for each machine so that computers can access each other.
2. Check if the Guest is denied access to the local machine from the network
When you open the guest account but still can't access it at all, please check if the setting is rejected. Accessing the computer from the network, because XP does not allow the guest to log in from the network by default, so even if the guest is opened, it cannot be accessed. Unlock the Guest account when the system Guest user is enabled. Click Start→Run. In the Run dialog box, enter GPEDIT.MSC, open the Group Policy Editor, and select Computer Configuration→Windows. Settings → Security Settings → Local Policies → User Rights Assignment, double-click the “Deny access to this computer from the network” policy, delete the “GUEST” account inside. In this way, other users can use the Guest account to access the computer using Windows XP system through the network.
3. To change the network access mode
XP default is to log all users from the network are handled by the guest account, so even if the administrator login from the network only Have the permission of the guest. If you encounter the situation that you cannot access, please try to change the access mode of the network. Open the Group Policy Editor, select "Computer Configuration→Windows Settings→Security Settings→Local Policies→Security Options", double-click the "Network Access: Sharing and Security Mode for Local Accounts" policy, and set the default setting to "Guest Only - Local User" Guest Authentication", changed to "Classic: Local users authenticate with their own identity."
So even if you don't open the guest, you can log in to the computer you want to access by entering the local account and password. The local account and password are the accounts and passwords already on the computer you want to access. If you need an account and password to access the network, you can log in by entering the account and password already on the computer you want to access.
Without access patterns change, maybe you even enter a user name and password are impossible, //computername /guest for the gray is not available. Even if the password is empty, you can't make sure to log in without opening the guest. Change to the classic mode, at least as long as the case of not opening the guest account in 2000, you can enter the user name and password to log in to the computer you want to enter. Maybe you will also encounter a special situation, please see the next one.

4. One noteworthy that we may encounter another problem, that is, when the user's password is empty, even if you do the above All changes still cannot be logged in, and access will still be denied. This is because, in the system "Security Options", the "Account: Local account with blank password only allows console login" policy is enabled by default. According to the principle of rejecting priority in Windows XP security policy, the password is empty. Access to a computer using Windows XP over the network is prohibited. We just need to disable this strategy to solve the problem. In the security options, find the "Local account with blank password only allows console login" item, disable it, otherwise you can not log in even if you open the guest and change to the classic mode. After the above changes are basically accessible, you can try to choose a method that suits you. Here are some additional questions you might encounter.
5. Network Neighborhood can not see the computer may often
can not see the computer you want to access the network neighborhood, unless you know the name or IP address of the computer , by searching or directly typing //computername or //IP. Please follow the steps below to start the "Computer Browser" service. The Computer Browser Service maintains a list of computer updates on the network and provides this list to computers designated as browsers. 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 is based on NetBiOS name The host name and address mapping methods are provided on the accessed network.
138/UDP--NetBIOS datagram, NetBIOS datagram is part of the NetBiOS (NetBT) protocol family on TCP/IP, which is used for network login and browsing.
139/TCP--NetBIOS Session Service, NetBIOS Session Service is part of the NetBiOS (NetBT) protocol suite on TCP/IP for server message block (SMB), file sharing and printing. Please set the firewall to open the corresponding port. Generally, it is only necessary to allow folder and printer sharing services in the firewall.
6. About sharing mode
shared XP default permissions given only to guests or choose to allow users to change the "My Documents." In the Windows 2000 operating system, users can easily set the shared properties of a folder. Just right-click on the folder and select Properties to see the Sharing Settings tab. In the Windows XP system setting folder sharing is more complicated, users can not see the sharing settings tab through the above operation. The specific modification method is as follows: Open "Tools" in "My Computer", select "Folder Properties", bring up the "View" tab, scroll to the bottom in the "Advanced Settings" section and "Simple File Sharing (Recommended) "The previous selection is canceled, and if there is a "Mickey Mouse" item in the options bar, the selection is also cancelled. After this modification, the user can easily modify the folder properties as with Windows 2000.
7.About the problem of slow response with network neighbor access
When browsing network neighbors in WinXP and Win2000, the system will delay 30 seconds by default, Windows will Use this time to search for remote computers for specific scheduled tasks (even possible to search the Internet). If the network does not respond when searching, it will fall into an unrestricted wait, so it is not surprising that the delay of more than 10 minutes is even reported. The following are specific solutions.
A. Turn off WinXP Schedule Taskr
You can open the "Task Scheduler" property dialog box in "Control Panel /Administrative Tools /Services", click " Stop the button to stop the service, and then set the startup type to "manual" so that the service will not be started automatically the next time it is started.
B. Delete the individual subkeys in the registry
Find the main key in the registry:
"HKEY_LOCAL_MacHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerRemoteComputerNameSpace"
Among them, the first Zijian determines whether the network neighbor wants to search for printers on the Internet. The second child determines whether you need to find the specified scheduled task. This is the culprit of the very slow online neighbors. You must delete this child.
Summary
Can not access mainly because XP does not open the guest by default, and even if the guest is opened, XP does not allow the guest to access the computer from the network by default. There is also a noteworthy question. I believe that some places that do not consider security or computer companies give people a system password is empty, but this is not allowed to log in. As long as you have tried the above methods, I believe that there will be no more problems.
