Problems with windows that cannot connect to this domain

Windows Server 2008 is installed in the VM and the domain environment is configured and the XP system is installed to join the domain. Today, after the virtual machine opened, the use of domain accounts to login to the XP client can not log on, check the configuration of IP, DNS, virtual machines and other configuration is correct, then try to reset the user password, disabled in the Enable account and other operations.

But still as the method of login, the more strange phenomenon is: login can verify the account and password, and according to the server configuration requirements reset password, but after the successful password reset, and prompted:

"Windows cannot connect to this domain because the domain controller is faulty or unavailable, or the computer account is not found, please try again later." If this message continues to reappear. Contact your system administrator for assistance.
