When you try to log on to a Microsoft Windows NT domain using only theTCP/IP protocol, the domain controller may not be found, generating thefollowing error message:
No domain server was available to validate your password. You may not be able to gain access to some network resources.
After this occurs, you cannot log on to the domain until you restart yourcomputer.
