Hi all. I'm a little concerned over this one. I am running vCenter Server v5.0.0 build 623373 and vSphere Client v5.0.0 build 455964 on 1 physical server . I have a total of 8 virtual machines running Server 2008 R2 Enterprise and 1 running Windows 7 Pro all of which are x64.
I logged into my vCenter VM today and found it grayed out at the host level with (not responding) next to the host and (disconnected) next to the vms. Under Alerts it shows 'Health status monitoring" & "Host connection and power state" ... I can right-click on the host and Connect and it reconnects and stays fully functional for about 5 minutes then goes back to not responding and disconnected.
Thanks for the suggestions.
