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. Because of this, other computers on the network may experience connectivity problems. For example, computers may not be able to authenticate to 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:
The computer restarts.
Netlogon begins to initialize.
The computer shuts down before Netlogon fully initializes.
