I'm planning a similar move this summer. At the moment we have a dual Xeon
2.8 with 1Gb of RAM running RH9 / Samba 2.x acting as a NT4 PDC. It handles
over 1000 students on 500 machine without any complaints.

I've just order a Dual Xeon 3 Ghz with 1Gb of RAM to run Samba 3 / OpenLDAP
so the Win2k/XP side of things shouldn't be a problem with the spec you've
mentioned. I can't talk about the LTSP side of things.

We have things like shared areas stored on another server again running rh9
with Samba and this authenticates to the main samba box. We then just map
the relevent drives as they login via a Kixstart script.
