I'd expect what's really happening is DHCP request goes out across the
network and both servers respond. The network booting machines may be
discarding the response which doesn't include network booting info or the
may just not have tripped up on a windows dhcp request yet. During boot,
the thin client again makes a dhcp request to enable the network card,
again getting two responses, it presumably takes the first of these. The
regular machines are presumably also getting responses from both dhcp
servers and probably discarding one in a not well described way (eg take
whichever comes first or second).
You should really determine what's going on for sure as this may cause you
subtle problems. tcpdump would be the obvious way to watch what's going
on. As you have separate ranges, you might check that your windows
machines are really getting windows dhcp addresses and the same for thin
clients (not at network booting, but when they're up and running). A
windows machine may remember its dhcp address, I think, you may need to do:
ipconfig /release
ipconfig /renew
or even reboot to get it to renew from scratch.
Perhaps I've misunderstood something here, but I don't understand how your
machines could intelligently choose one dhcp server or another.

That sounds very promising -- apart from the cd on the server popping up on
thin clients, which is bad.

This I have to see too. Could you post some screenshots somewhere?

I would have thought the vnc server must be running on the server and
therefore you would connect to the server with vncviewer. Maybe not
though. It's probably something like 192.168.1.25:13.

As a very quick hack, you could edit /usr/lib/ltsp/greeters/gtk and search
for the line:
markup = '<span size="10000"><b>Username:</b></span>'
which I guess should be modifiable to produce the desired effect. this
quote is from dapper, so yours might be a little different.
