RE: [ProgSoc] Win2K dropping off network

[Martin Gisch <martin@nospam.progsoc.uts.edu.au>]

I considered it was the NIC...but seemed like odd symptoms to
me. Still...worth a try to replace it.

Problem has never happened when I wasn't connected to VNC remotely.

Dis-abling and re-enabling the network works fine as far as it tells me,
but it doesn't fix the problem. Dis-connecting the patch cable also
doesn't pop up the little "LAN Disconnected" icon like it usually does.
