hmm, now that's interesting in it's own right....does the Win2K machine
have the right gateway address? if not it's going to be confused , and
anything it tries to access (even DNS) is going to make it try to go out
on the internet...also, make sure it has a name in the tcp settings for
the ethernet card, if it gets a dhcp address but doesn't know it's name
it's going to try to reverse the address to find out it's name, and it's
probably never going to succeed..

also make sire WINS is off, it's evil ;0

another thought, if you have ms networking installed it's going to do odd
things also...i've seen machines ask for netbios names that get translated
into broadcast requests and probably will get past the qube...

tcpsump looks at the network interface and prints out all packets that go
by...if you can telnet into that qube(which one) and can compile things on
it you can install it, there's probably a rpm around somewhere

ahh for the Qube2:

ftp://ftp.cobaltnet.com/pub/products/qube2/RPMS/tcpdump-3.3-2.mips.rpm


(no, there's no windows version as far as i know, there are windows based
packet tools but they tent to be expensive)

Get a cheapo puter and put linux on it, it's a lotta fun to play with :)
