Access denied by neighbors on the LAN

Lan network neighbor Access Denied problem Windows Lan sharing troubleshooting instance http://www.bkjia.com/ OS /201207/138257.html network for the problem described more, here is no longer tired. When there is a problem with sharing and access, consider the following steps: 1. check whether the guest account is enabled. By default, the guest account is disabled. To enable other users to browse your computer, enable the guest account. At the same time,
For security, set a password or permission for guest. Of course, you can also set a user name and password for each machine
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 the local machine at all, check whether the setting is to deny access to the computer from the network by the guest account,
By default, XP does not allow the user to log on from the network. After the system Guest user is enabled
To remove the Guest account restrictions, click "Start> Run", and enter "GPEDIT. MSC" in the "run" dialog box ",
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 to delete the "GUEST" account. In this way, other users can use the Guest account
Windows XP computers are accessed over the network. 3. Change the network access mode. By default, XP processes all users logging on from the network according to the Guest account. Therefore, even if the Administrator logs on from the network, only the guest
If you cannot access the VPC, 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 the local account and password to log on to the computer and local account you want to access.
And the password is your account and password in the computer you want to access. If you need an account and password when accessing the network, you can enter
The account and password in the computer to log on. 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. Change to the classic mode, and the image can be reached to the minimum
If the guest account is not enabled in section 2000, you can enter the user name and password to log on to the computer you want to access. Maybe you will
For a special case, see the following. 4. We may also encounter another noteworthy problem, that is, when the user's password is empty, you cannot log on even if you have made any of the above changes,
Access is rejected. This is because, in the "Security Options" of the system, "Account: A local account with a blank password can only be used in the console
The logon policy is enabled by default. Based on the Denial-of-priority principle in the Windows XP security policy, users with blank passwords can access and use it through the network.
Windows XP is disabled. We only need to disable this policy to solve the problem. In the security options, find "Use
A local account with a blank password can only log on to the console. This option can be disabled. Otherwise, even if guest is enabled and changed to the classic mode
You cannot log on. After the above changes, you can access them. You can try to select a method that suits you. I will add more information below.
Possible problems.
5. The network neighbor may not be able to see the computer you want to access in the network neighbor, unless you know the computer name or IP address, by searching
Or enter // computername or // IP directly. 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 you stop
This service is neither updated nor maintained. 137/UDP -- NetBIOS name server, the Network Basic Input/Output System (NetBIOS) Name Server (NBNS) protocol is TCP/IP
Part of the NetBIOS (NetBT) protocol family, which provides Host Name and Address ing methods on networks accessed Based on NetBIOS names. 138/UDP -- NetBIOS datagram. NetBIOS datagram is part of the NetBIOS (NetBT) protocol family on TCP/IP. It is used for network
Log on to and browse. 139/TCP -- NetBIOS session service. NetBIOS session service is part of the NetBIOS (NetBT) protocol family on TCP/IP. It is used
Server Message Block (SMB), file sharing, and printing. Set the firewall to enable the corresponding port. Generally, you only need to allow folders and
Printer sharing service. 6. For shared XP, the sharing mode only grants the guest permission by default or allows the user to change "my files ". In Windows 2000
It is easy to 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. Specific Modification
The method is as follows: Open "Tools" in "My Computer", select "folder properties", bring up the "View" tag, and go to "Advanced Settings"
Partially scroll to the bottom to cancel the selection before "simple file sharing (recommended)". In addition, if the option bar contains the "Mickey Mouse" item
Also, cancel the selection. In this way, you can easily modify the folder attributes like Windows 2000. 7. The system will be delayed by 30 seconds by default when Browsing network neighbors in WinXP and Win2000, and Windows will use this time to search for remote computers.
Whether a specified scheduled task exists (or may even be searched on the Internet ). If the network does not respond during the search, there will be no limit.
Wait, so it is not surprising that the delay of more than 10 minutes or even an error is reported. The specific solution is as follows. A. Turn off the Task sched of WinXP. You can go to "control panel, administrative tools, and services" to open the "Task Scheduler" attribute dialog box and click "stop" to stop.
Set the service type to "Manual", so that the service will not be automatically started next time. B. Delete the two subkeys in the Registry and find the primary key "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ RemoteComputer \ Name" in the registry.
Space "removes the following two child keys: {2227A280-3AEA-1069-A2DE-08002B30309D} and {D6277990-4C6A-11CF-87-00AA0060F5BF }. Among them, the first sub-jian determines whether the network neighbor needs to search for online printers (or even to search for the Internet). If the network
You can delete this key if no printer is shared in. The second child Jian decides whether to search for the specified scheduled task, which is a slow network neighbor.
The culprit 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 access from the network by default.
Computer. There is also a noteworthy problem. I believe that the passwords of systems provided by computer companies and computers that do not consider security are empty,
However, logon is not allowed. If you have tried the above methods, I believe there will be no more problems. Add: Under "Computer Configuration> Windows Settings> Security Settings> Local Policies> Security Options", "Network Access: Do not allow anonymous enumeration of SAM accounts and shares to" Disable ". shanblue
