Hi,
I have a fresh install of vcenter 5.5 on Windows Server 2008 r2, I added my hosts and everything was working great. Then I rebooted the server... now the service VMware Virtual Center Server constantly goes to "starting" state to "started", then back to "starting" and continuously loops. I've seen many others having a similar issue where restarting other vmware services fixed the issue, but this hasn't worked for me.
This is the error that I'm constantly getting in the event log.
