When changing a virtual disk (vDisk) in private mode to KMS activation and then changing the mode to standard image mode OR changing the activation procedure to KMS for a vDisk in standard image mode, the following error message appears, which can be seen in the console.log (when in debug level) or in the console popup: “Failed to map vDisk, no Driver”

The console passes a request to prepare the vDisk for KMS, which requires the SOAP service to update the vDisk file system and registry entries. This update needs the vDisk to be mounted. The Network Service account does not have SE_MANAGE_VOLUME_NAME privilege which causes an “access is denied” error when it tries to mount the vDisk.
