Damon,
If you're getting a blue/gray screen at the console, and you're able to
ping, then it doesn't sound like it's a NIC issue.
I know you've stated that SP1 breaks a 16-bit app, but SP1 was what
sorted out our very similar issues (No Citrix). You may be better served
by working out what it is in SP1 that the 16-bit app doesn't like, and
then applying it.
Do any of the affected servers not run the 16-bit app? If so, I'd
suggest SP1 on one of those and see if the issue recurs.
NIck

I would like to try ALB but the documentation I have states that
Spanning tree must be turned off, it is currently turned on. I need to
read up on spanning tree t understand why it is on.
My intel doc states..
ALB teaming requires that the switch not be set up for teaming and that
spanning tree protocol is turned off.
ALB does not balance non-routed protocols such as NetBEUI and some IPX*
traffic.
ALB teams can contain both 100 and 1000 Mbps adapters. The load is
balanced according to the adapter's capabilities and bandwidth of the
channel.
This teaming mode works with any switch.
ALB mode is not supported for Intel(r) PRO/10GbE Server Adapters.
