GP SRS Reports

I am running GP2010 and SQL 2008.

Have rolled out the GP SRS and Excel reports, but believe I may have messed up the security in an effort to tighten it up before all users see them.

Users who had access to the SRS web site (http://servername/reports) can no longer access that site.   These users also have lost the ability to view/add Metrics in the GP home screen.

Can someone please share the default SRS permissions (or SQL permissions) to see if I can get this started over again?

Thank you.
