We recently had a server with a runaway application that was storing temp files in the wrong directory so that they were just building up endlessly. After deleting these files and restarting the server (2008r2) RR can no longer connect with the SQL DB running on it. It claims the username or password is bad. I can still log into the SQL server directly with these credentials.
Any ideas? I am restarting the core now. I tired re-entering the creds into the core but no dice.
