assistant: Hello DAVID, on 07-24-96 you wrote to ALL  about 2 NICS IN NT SERVER:
AS you are using NT server, it is likely to be compute bound. My rule of
thumb is that NT requires around 6 times the computational horsepower
compared to NetWare. Using a Digital Alpha machine to run the NT server
on would likely help.
A second NIC might help a bit. Keep in mind that NetBEUI is a quite
chatty and inefficient protocol, and won't get you as good a file
transfer speed as you would get using Novell's IPX/SPX.
Your Cisco router sits in the intersection between Support LAN,
Production LAN and the Internet feed. Everything depends on how its'
routing/firewalling has been set up.
It would only increase the available bandwidth into the NT server,
which, if it is compute bound rather than I/O bound, won't do much for a
sluggish NetBEUI system. The data flows elsewhere, such as through the
Cisco router, will be the same as before.
My suggestion would be to rethink the Win NT server strategy. Either
upgrade to full multi processor SMT, run NT on an Alpha, or use the
existing NetWare server for the enterprise files to get some adequate
file service speed back into the system.
