[Samba] Samba, solaris, XP and active directory HELP!!!

[Ben Bays]

OK here is my situation.
The windows guys agreed that microsoft was wondeful so
they decided to upgrade everbody to winxp and and
active directory. That has messed with my file sharing
from solaris 6, 7, I only use samba for file shareing
of the UNIX file systems to the window ( xp) world.
Now I can even get acces to my files. 
I am running samba 2.2.8a

2 questions 
1. how can I makes my share show in the active
directory domain (the workgroup name shows up but I
can't drill down any further)

2. how can I make people use their unix passwords (I
am running nis) to authenticate as opposed to their
smbpasswd or AD passwd. 

Thank you very very much. Please help none of my
shares are showing.

below is a copy of my smb.conf
