RESOLUTION

To resolve this issue, in User Manager for Domains, remove the users or groups from the following user rights, and then run the suss.exe -install command to install a new service-based component: If you are upgrading over a previous installation of SU, Microsoft recommends that you revoke the privileges listed above from any users or groups that they were granted to previously. This can be accomplished in the User Manager (Usrmgr.exe or Musrmgr.exe):

2. On the Policies menu, click User Rights.
3. Click to select the Show Advanced User Rights check box.

   2. In the Grant To list, select the users or groups to remove, and click Remove.
5. Click OK to close User Manager for Domains.

The service component is encapsulated in the Suss.exe executable file, and this is installed by using the following command at a command prompt:
