What should I do if XP does not allow access when guest is enabled?

Many windows
When the XP system is enabled with guest, it cannot access the network. The Troubleshooting is as follows:

Why can't I access it if guest is enabled?

1. By default, Windows XP disables the Guest account

2. By default, Windows
XP's Local Security Policy prohibits Guest users from accessing the network

3. By default, Windows
XP's Local Security Policy-in user permission assignment, "Empty Password users 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, guest default Empty Password

Therefore, if you need to use a guest user to access windows
In XP, you need to set 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.

Access Windows
In XP, the username in the logon dialog box is gray and always a guest user. You 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, Windows
The access method of XP is "Guest only", so you can access it, of course, it is fixed that guest cannot enter other user accounts.

Therefore
The simplest method of XP is: You don't need to enable Guest, just change the security policy above to "classic. Access Windows from other systems
XP, you can enter your account information.
