[K12OSN] Window Clients can't get past the Linux Server

[Steve Jackson]

This sounds like a DNS lookup problem to me. DNS is used to locate 
domain servers in Active Directory, assuming that's what you mean by 
"tree server" - and the same for Novell I think.
To diagnose, I would hand-configure the W2K DNS server entry to be the 
same address as it would get if it were connected to the "main" network, 
and see if it now works. If it does, you need to look at where the LTSP 
server's DNS service is forwarding requests it can't handle to, and make 
it try the "main" network's DNS. If your LTSP server doesn't have a DNS 
service, change its DHCP config to tell the clients to use the main DNS 
address.

Transparent proxying only affects web traffic IIRC (and I'm not sure 
what's going on with squid, can't help there). The ip_forward setting 
must be 1. NAT must be used unless the "main" network knows how to route 
packets back into the "terminal & w2k" network.
