Duplicating Database from one server to another

[tkatlas]

I am trying to duplicate a production server to a test server and would normally just restore the user created database, say MY_DATABASE.&nbsp;&nbsp;Sometime when I do this I run into problems with user id's because the logins weren't the same.&nbsp;&nbsp;I tried restoring the master database, but ran into problems.&nbsp;&nbsp;First it had to be in single user mode which i did&nbsp;&nbsp;with sqlservr -m command.<br>Next, I tried restoring the Master database from a file and it said I needed to drop the database.&nbsp;&nbsp;Now, how do you drop the master database and be able to restore it.&nbsp;&nbsp;Any help would be greatly appreciated.<br>Thanks,
