jpaulus,
Thanks, I've picked up the dump. There's some weirdness in it:
- VM seem to have an IP of 10.211.55.3 initially which is just fine when Shared mode works, but as you say it doesn't
- There are no DHCP requests from the VM at all. If your XP is configured to use DHCP then DHCP discovery must take place after 'ipconfig /renew'
- At some point the VM decides to autoconfigure its IP to 169.254.*. This is weird given there were no DHCP discovery.
Are you sure you did 'ipconfig /release' and 'ipconfig /renew' while capture was running?
From the dump I'd say something is wrong with XP setup. Have you installed some third party network software besides Ethereal?
