Jun,

My experience with coax is with video, not networking, but as long as the
ends are terminated and your problem computer is physically disconnected
from the BNC T-connector, I don't see why the network shouldn't continue to
work.  I think the problem with coax networks is if a computer is CONNECTED
to the network but not working it will take the network down.

As for the problem PC, the usual troubleshooting techniques should work.
Rule out the card and the connection hardware by swapping with another
computer.  That leaves the software configuration on the PC.  Can you give
us more information on the type of networking being used?

I'm in hot water, please help.

The problem background: a customer called for PC service, as I checked, his
harddisk was going to die. so I told him to bring computer to my workshop.
since I started working on the harddisk, I also found the power supply fan
and CPU fan wasn't working either. I replaced the near-dead harddisk, CPU
fan and PS fan, load win95B and restore all settings (workgroup, protocols,
...). As required, I was asked to ensure the computer can connect into
network.
The problem: now, the computer couldn't see the network, in Network
neiberhood, sometimes it can see itself, sometimes sees nothing (not even
itself!). The harddisk is shared, and protocals and workgroup name are same
on other computers. The cabling is Coaxial connected to BNC T connector (end
with terminators). the strange thing is, as I understand, a coaxial peer to
peer network cannot work if the mid of cable is broken, but when unpluged pc
(and cable from back), the rest computer on network can still share printer,
harddisks, ..., the broken link didn't bring the network down! Customer said
he did nothing but unplug the pc so he can bring it to me, and the computer
as I saw before, was part of network. How could this be, how can this
network work? I need to make it work before weekend or I'm in deep trouble.

Anyone has any idea? please help.
