In some circumstances while updating resources on workstations the resource updating manager tends to hang and by attempting to stop the process leaves the resource updating manager in "Aborting" and proper functionality does not return.
This occurs even though the Resource updating manager service is stopped from the services applet.
1. Open Task Manager properties on the console.
2. Find the RCMD.EXE service and End task for this service.
This will release the Resource updating manager, allowing to perform future updates.
