Windows NT server 4.0 backups

I recently was hired as the server administrator for a company running 50 computers. Their backup server is running Windows NT Server 4.0. They run DOS scripts that create backup files to a building in another location. I am used to using server 2003. How do I run DOS scripts to create backup files to the off site computer? Second question is, that every time a new employee is hired their is about 14 scripts to type in and I was wondering if there is a way to where I only have to write one?
