A Microsoft Windows XP-based client may randomly register service (SRV) records in the Domain Name System (DNS) as if the computer is a new domain controller in the domain.

When the other computers on the network query for a domain controller, the Windows XP-based computer is returned together with the actual domain controllers. Connectivity problems may be most prevalent when the Windows XP-based computer that has registered SRV records is shut down.
This problem occurs because Netlogon incorrectly registers the SRV records if the computer is shut down while Netlogon is initializing. A Windows XP-based computer is more likely to experience this issue when the following conditions are true:
