Security requirements

by Sep 2, 2015

I have a sql instance on port 1450 which I cannot set up Idera to access. There is a default sql instance on the same box and I am able to add that instance to diagnostic manager. The ports have been open in the firewall per infrastructure. I notice that the diagnostic manager service account has SA privileges on SQL but does not have administrator. What is required from a security perspective for adding a sql instance and how can I best troubleshoot the issue?
