Server is using all my internet bandwidth

Intermittently my windows 2008 server is over using my internet connection and causing the the internet to be slow for the whole LAN.

I have established that the server is causing the problem by a process of elimination. When I turn the server off the ping times from the PCs on the LAN to www.google.com are fine. When the server is on the ping times go up to 1000ms and beyond.

How do I establish what on the server is using all this bandwidth. What tools are available on the server. I also have a sonicwall security appliance at the network edge connected to the internet.

I have been trying to get the bottom of this for months. Can someone help please?

Ive just realised that if i stop the edgetransport.exe process that problem goes away.

So it looks like the issue is related to my exchange server.

Any suggestions?

Big mails?
Use netstat -no and check the ESTABLISHED connections. Maybe the server is connected to the other mai servers?
