Configure Samba on Casper

The goal is to set up Casper as the PDC for our network. We were able to set up file sharing, but we did as much luck with the PDC configuration. The Samba book I have covers version 2.0, and Windows OSes through NT 4.0. We are using version 2.2.7a (with RH9), and the clients include Win2K and Win XP Home. Finally, on the Samba site, I found Using Samba, 2nd ed., which covers version 2.2 and all WIndows OSes out now.
