Restore DB from Disk File script

,

This script was designed to restore a backup of a production database from disk file, handle multiple DB files, move the files to new location, with new database name that is customized for the date of the backup, create any missing logins, and fix any user accounts that are orphaned by differing SIDs from the other server.
It has one area that is custom for my use, we create two user accounts and related roles, one is to allow 3rd party access (this reads minimal rights), and the other for internal application access (this reads full rights). These accounts are assigned to two roles. Which role defines how I create default passwords for new logins on my development server. You may notice that I like to make the login's default database tempdb, that way each time I restart the server, any objects created by the 3rd party login will be dumped when the tempdb is created.
Hey, works for me, especially for novice users.
