Hello,

having a weird problem here and wondering whether anyone has seen something
similar...

I needed to install an XP-PC in a building that is somewhat seperate from
the rest of the company, and only attached to the network via a 10base2-link
(3Com hubs with BNC-connector, one hub itself connected to a 100Mbit 10BaseT
backbone switch)

I could not make the PC connect to the network. A few years ago we had some
NT4 PCs working over this exact same connection. Since it hadn"t been used or
changed for some time I suspected a hardware problem somewhere and started
replacing hubs, T-pieces and terminators, to no avail.

To make sure that I was using good hardware, I then decided to first make a
small network with the two hubs, a piece of coax/10base2 cable and the needed
T-pieces and terminators. So I connected the 2 hubs via the coax, plugged a
PC into a RJ45-port in each of the hubs, assigned fixed 192.168.0.1 and
192.168.0.2 addresses and tried to let them ping eachother. It didn't work!

The very strange thing was, that I could clearly see activity on hub2 when I
pinged from the PC on hub1 and the other way around, PLUS: they COULD see
(ping) each other as soon as I used UTP cables to connect the 2 hubs!

So everything pointed towards the coax-side of things. Yet, all LEDs were
normal, I tried several different hubs, cables and T-pieces/terminators...

Now I was wondering that maybe XP Pro may have issues with the old 10base2
technique? Although I would expect total transparancy (certainly since the
PCs themselves were connected via UTP, and only the hubs interconnected via
10base2)

any ideas?
