Looking into this further... forget what I just said. The problem appears to me as though the issue is that there are entries in your master.dbo.sysdatabases table that are invalid. In other words, the database 'ARIS7' that shows up in this error message exists in your master.dbo.sysdatabases, but does not actually exist on your system. Is this the case? What is happening is the cursor is not being defined because the table 'ARIS7.dbo.SysUsers' is not being found. That's all I can figure without actually looking at your system.

Let me know what you find out.
