vcenter service will not start after changing service account to local system

[tdubb123]

I got a 5.1 vcenter that will not start after changing the service account to localsystem

I see in the vpxd logs saying

Login failure

Failed to connect to database

I checked my odbc connection and its using a domain\serviceaccount

but once I change my service account to domain\service account

vcenter services start up fine

any idea why I cant use the localsystem account instead?
