I used ZCC to deploy the 10.3 update to the ZCM server and it has "assigned" status and it said I have to refresh the device.

The ZCM server is a SLES10 SP2 server. On ZCC, Devices > Servers, the server has last contact date Jan 13 and the cloud icon. Why? My agents all has the current contact day.

How do I fresh the server? Use what parameter with zman?
