Yes everything is on the same flat network. Servers occupy XXX.XXX.2.X, while printers, phones, computers, consoles (except the PS3s) occupy XXX.XXX.5.XXX, PS3s are XXX.XXX.4.XXX. The phones are on seperate switches, but they still are connected to a main switch where the internet comes in.

This in my opinion is a network that just grew too fast and wasn't planned out as well as it should. My job now is to find out why our app server is so slow and I have a feeling it is the network and the amount of data being pushed over and over through the dumb switches.

No VLANs are in place and very little segregation is in palce. The uplink from each switch is 1 Gb and I am not sure if we are really exceeding bandwidth as much as pushing so many requests from all these nodes simulataneously.
