How to change the service account for the Vmware Vsphere Virtualcenter server

The next thing is to create a login for the Service Account on the SQL server that is hosting the database and give the user dbo_owner permission on the vmware vsphere database. The thirth step is to create a ODBC connection to the database. Therefore you have to log on under the system account and start the ODBC Administrator.

You may get the message that the service account has been granted the “Logon as a service” right. When the action completed succesfully, you should see the following:
