What versions are you running.. I have seen this when the host agent dies. I think it was a 3.02 box from memory
i think i had to kill the vpxa service and restart it from within the host (using ssh). I think there was a kb article about it, but i cant remember where right now I'd be interested to know if the host is part of a cluster and if so removing it and re-adding it helped. also you can edit the xml file and turn up VC logging to give you more info, but i dont have that handy at the moment. I documented it for work but im not there right now Greg ________________________________ From: James Rankin [EMAIL PROTECTED] Sent: Friday, 3 October 2008 7:39 PM To: NT System Admin Issues Subject: Virtual Center query Does anybody have any idea why sometimes some of my ESX servers show as not responding in VirtualCenter, and the guests running on it show as disconnected? The guests themselves are still up and running fine, but they won't respond to VirtualCenter commands (all the options are greyed out). The only way to get around this seems to be shut down all the guests on the affected server, and then restart the ESX server - not really an option when my Exchange, Excalibur and SQL servers are running on this particular ESX box. If ESX was Windows, I guess I'd be looking for a failed service or something, but being a bit of a Unix/ESX amateur I'm not sure where to start troubleshooting....
