I was experiencing the same problem along with the performance overview would not
function. I was running the Vmware VirtualCenter Service and the
Vmware VirtualCenter Management Webservices under a domain
user account account. Going into the Local Security Settings of the server
(Go to Control Panel, Administrative Tools, Local Security Policy) and adding the
domain user account to "Act As Part Of The Operating System", and "Log on as a service"
fixed all the above issues. Thanks to all the help in this group.
I am running vCenter 4.0.0 build 162856 (with Update manager and converter installed)
