New to this. Please Help. I have a Winbdows Server 2003 DC and a Exchange 2003 Box. We are using mostly GB NICS in each Client. The question I have have is would it be a large increase in speed and bandwith if a used GB Fiber Optic connection from my Servers to my main switch. I have 40 PC's lots of inter net usage and lots of email comming through a local T1 line (1.5mb). I cant help to think that I have a bottle neck situation.
