Exchange 2007 Edge role & Internet bandwidth performance
Posted on 2009-04-16
Suddenly our Exchange Edge servers which are running as virtual machines using Win2008 OS on top of host using hyperV manager started to utilize all our internet bandwidth to an extent that our internal users are not able to brows internet any more (its deadly slow).
The time we switch off both ETRs internet bandwidth get free and users start to access internet normally.
We noticed switch ports connected to ETRs are blinking very fast, we suspected its virus but we run Symantec and nothing has been dedicated.
Also we did tests to check if our ETRs are open relay but results shows that it cant be relayed.
Any thoughts can help
