I backup an SQL Server 2000 database (MY_DATABASE) and restore it in
SQLServer 2005.
Then, when I try to access its properties I get:

Property IsPrimaryFile is not available for DataFile '[MY_DATABASE]'. This
property may not exist for this object, or may not be retrievable due to
insufficient access rights.  (Microsoft.SqlServer.Smo)

- I'm using a windows 2003 administrator account
- I tried setting compatibility level to 90 but it didn't help.
- If I connect with a sql-level user (not windows 2003 login) a can view the
properties, but I can't change anything.

Any ideas?
Thanks!
