To add to the conversation that Tony and Christopher are having, I seem to recall another "gotcha" with changing the default database from master (though I still do it). It had to do with a wizard not finishing due to an error. I wanna say it's the Restore Database wizard but I've tried searching the interwebs and I'm not finding it. Nevertheless, when it happened to me, I searched the exact error code, discovered the solution in short order, changed the default DB back to master and the wizard completed...in fact, now that my fingers have said this "out loud", I recall having to change the default to something OTHER than the DB I was trying to restore...yeah, I think that was the problem. Nevertheless, changing the default DB was the 'gotcha' but it's so minor I'll stop clamoring on about it. :-P
Nice articles by the way. Thanks for writing them, Don.
