I noticed from the SQL Server log that every time server restarts (I'm using SQL Server 2008 developer edition) I get an error message into log:
Login failed for user 'machine\sqlaccount'. Reason: Failed to open the explicitly specified database. [CLIENT: <local machine>]
I can see details from the profiler trace and it shows that the application causing is Report Server and the database is master. How should I modify these privileges to get rid of this error?
