Hilft das:
If a backup domain controller (BDC) is running Windows Internet Name Service (WINS), the following event error may be logged when you start the BDC:
Event ID: 3096
Source: Net Logon
The Windows NT Domain Controller for this domain could not be located.
Approximately 30 seconds after the startup process is complete, the BDC is once again accessible.
CAUSE
This problem occurs because WINS is starting too late in the process for name resolution to occur.
RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this problem, edit the registry and create a dependency for WINS in the Net Logon service:
Start Registry Editor (Regedt32.exe).
Locate the DependOnService value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\
On the Edit menu, click Multi String, type Wins to add it to the list of dependencies, and then click OK.
Quit Registry Editor.
Restart the computer.
