one reason is because lots of things depend on netbios names in Windows
95/98/NT networking. each computername is used as a netbios name. each
netbios name has to be unique, so requests "I need the mac address of the
computer with netbios name whatever" can be answered by only that machine.
if you have one server with two nics on the same network each of the nics
tries to register the computername and they fight with each other. try
changing a windows 98 machines computername to be the same as another
machine on the same network and you'll get an error about a duplicate
computername and the second one will not be able to get on the network, same
thing.
In NT there are ways around it, look at the netbios tab under the bindings
tab for one of the nics you can disable the wins client. I think this stops
the nic from trying to register the name.
It's better to not design something like this in the first place. If you
want the second nic for fault tolerance, look for a solution that binds the
two nics into one logical nic and one mac address
probably someone can give a more technical explanation...

I was a bit curious about that myself. Of course I am Windows-centric.
The one thing I never did understand in the WinNT world was why one could
not have two NIC's in a server, and assign both NIC's into the same subnet.
Could be done easily in the IPX world on a Netware box.
Any thoughts?
