Step by Step login script setup help

I am just delving into NT and I need some step by step assistance. I am humbly asking for some hand-holding guidance.
The environment I am setting up is a 1 w2k server (all updates, active directory is on, DHCP is on, DNS is on, and setup as Primary Domain Controller) 4 winxp pro clients. All my goal is, is to setup file sharing and internet sharing from the 2k server to the xp clients. I have the internet sharing down. the file sharing is where I am having difficulty. I want to setup a login script for all my users to share out 3 shares. 1 is a public dir for documents, 1 for user profiles and 1 for the medical app. (I know what I have to share). I need someone to give me some step by step instructions on how to accomplish this. #1 Where on the server do I put my login scripts? Is this put locally on the clients? If so where? If not, where on the server should they reside? I want a dos box to pop up on the screen after I login to the domain and show all the mappings. What syntax do my login scripts need in order for them to map to the right share. #2 How do I know and what do I check to ensure my dns is functioning correctly so my clients recognize my domain?

This is all that I need. I would appreciate any help given and would welcome any solutions to my issue. I need clear and a concise answer please. Dont assume I know anything except basic networking.

My domain is "DENTIST"
My DC dns name is "SERVER"
My public share is "Idontknow,whatshoulsitbe?"
My app share is "c:\program files\dentrix\" Whats the syntax for this when I put this in my login script?
My client names are "Front1", "Front2", "Doctor", "Back1"

Any other information can be given. PLEASE HELP ME FOR THE LOVE OF GOD! THANKS A BUNCH!
