I have 4 ZCM servers in my environment. All are SLES 10.2 running ZCM 10.2.2

Updates have completed successfully, according to ZCC.

It's been over a week since i updated to ZCM 10.2.2.

Servers are not communicating with ZCC now.

When i click on a server object in ZCC, it tells me Unable to connect through IP Address or Host Name.

When i go on the SLES servers and type "zac ref" or zac ref bypasscache i get "Exception: Connection Refused"

On the SLES servers I have rebooted numerous times. These servers were working fine before ZCM 10.2.2.

Any assistance would be appreciated.
