Details

The issue is about getting an exception when reading data from the registry. To fix this issue, the user must remove the registry values to force the Policy Server recreate the values. Do the steps below:

Open the Registry Editor, then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Mobile Armor\DirectorySync\DNs.
Delete all of the values, except "(Default)".
Restart the Policy Server Windows Service to trigger AD Synchronization
