Is the NIC and the Raid controller sharing the same IRQ by any chance?

Everything is within the same Lan, workstation to server pings are
returning < 10ms. Our latency issue is certainly worse when the CPU
utilization is above 50%, but there is no memory bottleneck and typically
cpu usage runs below 30%. We have had the latency reported before 8 am
when there are less than 5 users on and high CPU usage is unlikely(not
impossible I suppose). I do keep taskmgr running to monitor the
performance throughout the day.
We have disabled the time zone, but not looked at the hotfixes mentioned in
other messages as they relate to Win2K server and we are running on NT.
The array controller issue mentioned is interesting as I am quite certain
we are using the Compaq SmartArray 431 controller. It is something for us
to look at anyway.

I take it all of the servers are on the same local area network from where
your users are logging in from? It may sound silly, but what kind of ping
times do you get from your workstation to the server? If its on the local
network, I cant see network latency being a big issue unless the network
itself is congested. Have you checked to make sure the processor and/or
memory arent bottlenecks?
