I would start to check on the View Agent side, can it resolve the connection-server properly?
Also have a look in the registry in the guest what connection-broker i is supposed to be talking to.
Its usually in: HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Agent\Configuration
Look for what it says on "Inital Broker" and "Broker"
If that looks ok, have a look in the View Agent logfiles for any clues.
