Update:
We tried again after motherboard replace and we had worse issues.
It appeared to be fine in Parallel testing mode, but when thrown into live environment with heavy load and traffic, lots of things did not work and connectivity to servers or the firewall web admin were slow.
We did here from a consultant who helped troubleshoot say that the Broadcom NIC cards have issues and Intell should be used.
Has anyone else experienced this issue?
Dell 1950 Poweredge server or problem with Broadcom NIC's
ready to buy a 4port Intel nic card and hopefully that will be it.
Link to new thrhead in Interoperablity.
