Missing words... Debian Server + Roaming Windows Users?

I'm not quite sure how to search or approach this as I'm not a
sysadmin, and therefore not sure what exactly it is that I'm looking
for...

Basically, I have a Debian (Sarge) server set up as per the howtoforge
"Debian Sarge - The Perfect Setup". I then have an XP box behind it
(ICS + NAT) which runs my music making programs, so I can't switch
(although I have Kubuntu in VMware for serious work). Okay, but knowing
Windows (actually just reinstalled after having more than twenty
trojans because of the IE Window() JS exploit), I also know that this
thing is gonna crash faster than I can say "balloon"... Windows won't
let me mount c:\Documents and Settings from a samba share, like i use
NFS to mount /home from my Debian server.

I'm looking at
http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/xpusrdat.mspx
right now, and I think that's what I want, but I don't quite now what
it's all about... I basically just need my settings and my documents to
be stored on my Debian server (which already has an "administrator"
user set up) so that when I have to restore the bugger (doing periodic
backups of the C: partition using knoppix) I won't loose my settings
and docs here.

Please, does anyone know of a (preferably simple, although I'm not
exactly computer illiterate) howto or tutorial of how to make XP store
documents and settings on a linux server?

Thanks in advance,
Daniel
