After you detach a Microsoft SQL Server 2005 database that resides on network-attached storage, you cannot reattach the SQL Server database. Additionally, a message that resembles the following may be logged in the Application log:
Msg 5120, Level 16, State 101, Line 1 Unable to open the physical file "\\servername\sharename\filename.mdf". Operating system error 5: (Access is denied.).

↑ Back to the top


This problem occurs because SQL Server 2005 resets the file permissions when the database is detached. When you try to reattach the database, it cannot be attached because of limited share permissions.
