So I have a Local Government Model schema SDE geodatabase and every time I try to use the "Create Role" data management tool, I get an Underlying DBMS error. The geodatabase is stored in SQL Server 2008 R2 SP 3. I've attached the error message to this thread. Someone please tell me why this is happening. I don't want to have to use SQL Management Studio to add roles to DBs, but I will if ESRI's tool doesn't work.
