SYMPTOMS
User name mapping may become inconsistent across cluster nodes in a cluster environment.
CAUSE
This problem may occur if the User Name Mapping service starts without recognizing that a cluster exists. If this occurs,, changes that are made before the cluster is initialized may not be propagated to all of the cluster nodes.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. WORKAROUNDWARNING: 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 prevent this problem from occurring, add a dependency to the User Name Mapping component. You can make User Name Mapping dependent on the start of the Cluster service by editing the DependOnService registry value. Follow these steps on all the cluster nodes:
- Using Registry Editor, locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mapsvc - Edit the DependOnService value. Add ClusSvc to the list of services.
