I have a VCenter 5.1 server that I had to rejoin to the domain. The DC died and I had to rebuild the domain controller from scratch. It's early on in the environment build and the user did not have backups running yet. The SQL database is on another VM which I re-added to the domain and at least I think I've fixed the AD accounts on the SQL server. I can ping the SQL server from the vcenter machine. I also have a webserver that is using the SQL server and it's working properly. All thought the web server is using a SQL account and not a Windows account. That being said this is the VCenter error I get. I'm not sure where I can pull more detailed logs. The VCenter service dies as soon as I try to start it.
Here is the Event Log
