How can I check which SQL Server instance my SCVMM installation is using?

Q: How can I check which SQL Server instance my SCVMM installation is using?

A: The easiest way to check which SQL Server instance your SCVMM installation is using is to look at the registry on the SCVMM server:

1. Start the registry editor (regedit.exe).
2. Move to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings\Sql.
3. Look at the InstanceName and DatabaseName values for the SQL Server instance and database name. The ConnectionString value shows the complete combination.
4. Close the registry editor.
