OK thanks for the info. I'll just remove Plesk from all of my IIS machines, because the SQL Server running just for Plesk is sucking up too many resources.
We have two Windows Server 2012 R2 servers. One is running our SQL Server and the other is running IIS hosting our web site.
We have Plesk 12 installed on both machines. We have an instance of SQL Server running on the web server and its entire purpose is to host the PSA database for Plesk...
