PVS Soap service member of Local Administrators on Server

 

For PVS images that use KMS, when you switch modes from Private to Standard and select Key Management Service on the vDisk, the PVS server performs a volume operation on the server that requires elevated privileges, specifically the ability to perform volume maintenance tasks.

If you are running Soap/Stream as Network Service or a custom account, it not have the permissions required.

You can test the GPO \Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment\ “Perform Volume Maintenance Tasks” but I have not.
