That error is usually received when you do not have permission to write to the directory that the database is located in. Contact your administrator and have them resolve your problem, if your administrator is anything like mine, you will just end up resolving the problem yourself. Have fun...

Check what user you are connecting as. Chances are the IIS_User does not have write permission on the directory your database is in. You don't need to give the IIS permission on the directory, just the database AND the temp directory should do fine.
