Domain Controller Takes a Long Time to Respond to a Logon Request, or It Does Not Respond at All

When you try to log on to your domain, the domain controller may take a long time to respond to the logon request, or it may not respond at all.

If you view the tracing information on your domain controller, you see that the server does not respond to the C Session Setup and the X SMB commands.

This problem may occur if the NetBIOS name and the DNS name of the domain controller server are different. If the names are different, a request is sent by the browser service to what is recognized as a different server. However, because the name will resolve back to the server that made the browser service request, the browser service is put in a locked state while it tries to resolve this name. While it is in this locked state, the browser service holds a lock that must be returned to the server service before a connection can be made, and therefore the server service stops responding.
