I have the following situation :
4 servers SLES 10SP2 with ZEN 10.1 all primary.
The first server was manually updated to ZEN 10.1.3.
The other three server got 10.1.3 automatically. There is only one server that keeps saying at the Assigned System Updates : Update for ZCM 10.1.3 status unknown.
The other two server say Update Completed.

What could be the problem ?
