Group NT permission problems
SQL error 15404: Could not obtain information about Windows NT group/user 'domain\beana', error code 0x5.
When using SSMS or SQLBU gui, I receive this error when attempting to backup databases that reside on a SQL server in our QA domain. Our domain is fully trusted to the QA domain, but the QA domain can not talk back to us.
The SQL Backup Agent is running under the same account which is running SQL Server in these domains (which are domain admins).
We connect as part of NT groups from our domain. We use AD to manage several layers of groups with different access. I am connected through BUILTIN\Administrators as I have box administration rights. I've also tried through a SQLAdmin group. Both return the same error. When I give myself direct permissions domain\beana on the instance, it works without problem. So it looks to be a problem with NT groups.
