1. generally, this problem starts-> Run-> gpedit. MSC-> Computer Configuration-> Windows Settings-> local policy-> User Privilege allocation-> Delete the Guest user in "Deny Access From the network to this computer"
If the firewall or server service is not started, the account is disabled.
1. open "my computer", choose "Tools"> "Folder Options"> "View" from the menu, and clear the "use simple file sharing (recommended)" option. Unified IP addresses are set for each server in the network.
2. right-click "my computer", select "manage", select "local user and group"-> "user", right-click the Guest user, and select "attribute ", clear the "Account Disabled" option. The XP firewall has been disabled.
3. click Start> Run and enter secpol. MSC, select "Local Policy" on the left-> "User power assignment", and double-click "access to this computer from the network" on the right to ensure that there is everyone, double-click "Deny access to this computer from the network" on the left to make sure it is empty. You have also tried to add or delete a guest user.
4. select "Local Policy" on the left-> "Security Options",. confirm "network access: the sharing and security mode of the Local Account" on the right is "classic"; B. confirm "Microsoft Network Customer: enable digital signature for communications (always)" on the right is "disabled"; C. confirm "Microsoft Network Customer: enable digital signature for communications (if Server permits)" on the right is "enabled"; D. confirm "Microsoft network server: enable digital signature for communications (always)" on the right is "disabled"; E. check that "Microsoft network server: enable digital signature for communications (if allowed by the server)" on the right is "enabled ".
1. Enable the Guest account
In many cases, for the security of the local system, the Guest account is disabled, so that you cannot access the shared resources of the machine. Therefore, you must enable the Guest account.
2. Modify the User Access Policy
Click Start> run, and enter gpedit in the run box. MSC. In the Group Policy window, expand "Local Computer Policy → Computer Configuration → Windows Settings → Security Settings → local policy → user rights assignment" (figure 1 ), in the right column, find the "Deny access to this computer from the network" option, open it, delete the Guest account, and then open the "access to this computer from the network" option, add a guest account in the Properties window. In this way, you can use the Guest account to access the shared resources of the machine from the network.
3. Correctly configure the Network Firewall
Many machines are installed with a network firewall, Which is improperly configured. Users cannot access the shared resources of the local machine. In this case, the NetBIOS port required to share resources of the local machine must be opened. Taking Skynet firewall as an example, in the "custom IP rules" window, select the "allow LAN machines to use my shared resources" rule, and click "save, in this way, the NetBIOS port is opened.
4. Set Reasonable User Access Permissions
Many machines in the network use the NTFS file system. Its ACL function (Access Control List) can control user access permissions. users need to access the shared resources of these machines, you must grant the corresponding permissions. For example, if you use the Guest account to access the CPCW shared folder of the machine, right-click the shared directory, select "properties", switch to the "Security" tab, and add the Guest account to the user list, specify the access permission for the guest, at least grant the "read" and "list folder directories" permissions (figure 2 ). To allow multiple user accounts to access the shared directory, you only need to add the everyone account and grant "read" and "list folder directories" permissions, this avoids adding and specifying each user's access account one by one. This method is applicable to Windows 2000/XP/2003 systems that use the NTFS file system.
First, the question about why guest cannot be accessed:
1. By default, XP disables the Guest account
2. By default, XP's Local Security Policy prohibits Guest users from accessing the network.
3. By default, in XP's Local Security Policy-> Security Options, "account: users with empty passwords can only log on to the console" is enabled, that is, any account with a blank password cannot access from the network and can only log on locally. By default, guest has a blank password ......
Therefore, if you need to use a guest user to access XP, You need to perform the preceding three settings: enable Guest, modify the security policy to allow guest to access from the network, disable the security policy in 3, or add a password to guest.
Sometimes you may encounter another situation: when accessing XP, the username in the Login Dialog Box is gray, always a guest user, and cannot enter another user account.
The reason is that this security policy is at odds (Administrative Tools> Local Security Policies> Security Options> "Network Access: sharing and security modes of Local Accounts "). By default, the XP Access Method is "only guests", so you can access it, of course, it is fixed that guest cannot enter other user accounts.
Therefore, the simplest way to Access XP is: you do not need to enable Guest, just change the security policy above to "classic. Other systems can Access XP and enter their own account information.
