We all know the master database in SQL Server 2000 was split into two databases in SQL Server 2005. One kept as Master only and the other database is Resource database which is hidden. You can’t see that in Management studio or in any tool. You can see the physical files in Data ( default )folder. The idea behind this separation of objects is to allow very fast and safe upgrades.
If you want to see what is inside this database follow these steps
(a) Stop SQL Server
(b) Copy /paste mssqlsystemresource mdf and ldf files to a new location
(c) Create a new database by Attaching the files from the new location
Now you have the hidden database right in front….
