Primary Domain Controller loses DNS until an admin logs into the server

I have a PDC, Windows Server 2003, that has had a sporadic issue lately. It seems like it loses DNS which "fixes" itself when an admin (Domain or local) logs into the server. Then everything using DNS seems to be fine. (Exchange, intranet sites and so on). I have several errors in Event Viewer related to multiple identical login Event ID 11 (SQL and reporting servers), Master Browser election errors (Event ID 8003). I'm not sure why it suddenly returns to normal when a user logs into the server, but that seems to fix it (temporarily).

Verify those services are running a service account and not as a disabled or non admin account.

Verified, all running as local system account, not interacting with the desktop.

Do you have DNS services running on another DC in the cluster? I am referencing Event ID 8003. That could be very problematic for DNS if another server is trying to become the master or PDC.

Take a look through these instructions:
1. Look at the System Event log on your server and look for the error 8003. Within that log, identify the “computer” that is announcing itself as a master browser.
2. Go on to the computer identified in step 1, go to the Services Administration panel. You can usually find this by going to Control Panel -> Administrative Tools -> Services.
3. Once you have Services open, look for an entry called “Computer Browser”. If that service is “started, ” you have found your culprit. If not, you may have to try the registry hack listed in step 6.
4. Double click on the “Computer Browser” service to edit it. Stop the service and then change the type to „Disabled” (from either Manual or Automatic). Click OK to apply your changes.
5. That should have resolved the issue. You should check your main servers event logs periodically to be sure that the error does not show up. If the error continues to appear read step 6.
6. Check the following registry value on the computer: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\IsDomainMaster". Ensure that it is set to false. You probably have to reboot the machine to make the change take place.
