Running a Dell Dimension 3000, with built-in LAN adapter.

When running Suse Linux 9.2 on the machine, I tell Ethereal to operate
promiscuously, and I can see all the traffic on the LAN segment.

When I run Ethereal under Win XP Pro (with all the updates), again with
promiscuous enabled, all I can see is broadcast traffic and any traffic
to/from the Dell.

So it's obvious that the network adapter is not actually running
promiscuously under Win XP, even though I enabled it in Ethereal.

Any ideas on how I can persuade Win XP to switch the NIC into
promiscuous mode?
