Question : System Center Essentials 2010 - Unable to connect to the Virtual Machine manager server.

When opening SCE 2010 - System Center Essentials I get an error that says Unable to connect to the Virtual Machine manager server.

When you click on close the application closes.

When you click on show to show the error and it says:

Application: System Center Essentials

Answer : System Center Essentials 2010 - Unable to connect to the Virtual Machine manager server.

Change the account the SQL Service uses to a domain user account, and also check the ownership (dbowner) of the SQL database VMM is using. Change this to the "sa" user or any other user with appropriate permissions.

Restart service to take effect.
