Exactly the same problem here.
Some machines are still in startup..
It was working all normally earlier but in one day its stopped
I cannot find any relationships why its so... No modifications was made to the system...
Only helps - is to restart Vmware View Connection Server service in services...
Tried to recompose (with advices mentioned earlier) no success.
Both Agent and Connection Server is 5.2
BTW - if let the machine in STARTUP and do not restart the service - it became available after several hours. (i think this is to much)
Looked also at the logs.. Nothing..
