I have a SLES 10 SP2 server (no OES components) running ZCM 10. I have the following in Available System Updates:
Jan 2009 PRU - status - Available
Update for ZCM (10.1.2a) - status Ready
Update for ZCM (10.1.1) - status Baselined

Under Deploying System Updates I have:
Update for ZCM (10.1.2a) - Pending

When I go to the server under Devices, it shows that the Last Full Refresh was Dec. 9 and that its Last Contact was Dec. 10. I am not able to refresh the server nor am I able to register any workstations (and was able to in the past). I'm assuming this is all related some how and would appreciate any suggestions.
