Question : Problem: Could low memory on an exchange/file/domain controller cause bandwidth to crawl to nothing on the entire network?

Could anyone point me to info that would support that low memory on a server could lead to killing your bandwidth.  I had a server that out of the blue decide to eat all of the memory and as a result my bandwidth died.  After 2 weeks of trying to sove the bandwidth problem I found the memory usage on the exchange server was through the roof.  I doubled the ram and fixed the page file issue it cause by eating up all of the remaining space I had free on the C drive and my bandwidth problem has magaically gone away.  I would love to think the memory caused the bandwidth, but I can' t find anything to support that.

This turned out to be a bad cable modem.
