Service Pack 3? There's all kinds of TCP/IP fixes since then. Get SP6a if
company policy allows you to. Also if you're using it for a router, are you
just using route add statements or are you using RAS or RRAS? RAS and RRAS
also need SP5 (I think) or higher to be stable. Actually RRAS wouldn't work
at all for me earlier service packs. I'm guessing at which one you need to
make it stable but it's posted in the white papers on microsoft.com.
If you can't upgrade the service pack, install SP3 again. Maybe something
overwrote shared system files.
Also check your bandwidth utilization on the server. If NT is used as a
router you need a seriously fast machine (especially bus speed) to handle
anything close to full capacity of the NIC. I like NT very much but I'm not
afraid to admit that it stinks at TCP/IP transfer speed. With a crossover
cable between 2 boxes with no other traffic I only got 6 to 12Mb throughput
on 100Mb cards. But then again it had a 66Mhz bus so maybe that had
something to do with it.
Is the NT Server doing routing or is it also doing some kind of client
services to connect users to shared resources on the AS400?
Hope I can help you out here.
