Are you certain that all boxes are configured to that netmask?
It's a basic question, but it could make the difference.

Is the netvista the only machine that isn't 10.1.2.x ?

I've never heard of someone seeing this and it being a Linux
issue.  It is far more likely to be a configuration issue.  There
is a way to make this work, the question is simply what.  So,
until someone with more experience chimes in, I'll continue
shooting in the dark:

1) I'll assume that your hub has lights, most do.  When you ping
   from the RH to the Win2K, the light for the sender and
   reciever flicker.  What about when you try to ping from RH to
   netvista?  How about the other way around?  

2) Do you have any services running on the RH box?  ping, a type
   of icmp protocol, isn't working.  How about http, ftp, smtp,
   telnet, shh or something else that uses tcp or udp?

Background :  how are the boxes getting their IP configs? static,
dhcp?  What is a netvista?
