Ok, couple of people to address:
Kore: NCREN always lets us know when they are making a change, no changes have been made recently to any thing.
Ex: The server is connect Via Cat6 (gigabit) to the ResNet Cisco 6509 router. The box has a seperate interface and the rest of the network comes in on 4 seperate interfaces. Traffic is then routed through our external Firewall and then out to the Cisco 6509 (NCREN) edge router (internet).
