[ILUG] Windows XP and VLANs?

[Adrian Wooster]

Having given up trying the MS route, could anyone help me with this oddity?

I have the simplest of networks - 1 XP laptop, and 1 Redhat 7.1 PC with
either a cross-over cable or **dumb** hub between.
    - Addressing, etc. is correct
    - Network cables, etc all checked

The problem:
tcpdump on Redhat sees traffic from both machines, but the Redhat machine
never responds to requests from the XP machine.
The XP machine responds to requests from the Redhat machine - tcpdumps sees
it, but ping, telnet, etc ignore it.

The only oddity I can see is that the packets from XP all claim they are in
801.1Q VLAN#0. There is no reference to VLAN's anywhere I've found on MS.

I'd love to get rid of MS altogether but unfortunately its a prototype for a
commercial project where MS clients are unavoidable.

Any help?
