Guest Mark Posted May 23, 2008 Posted May 23, 2008 We are having a problem with "something" on our network consuming all of our internet bandwidth. It is an intermittent problem but becoming a REAL problem. We suspect that the culprit may be our Windows SBS 2003. Does anyone know of a utility or tool which I can install on my server that will show specifics of what process(s) are using bandwidth, and how much? Thanks.

Just a hunch ... next time you observe it happening take a look at the exchange output queues on your server. If they are full of non-delivery reports then its a reasonable bet that your server is being used to delivery Reverse-NDR SPAM(for details see http://www.cryer.co.uk/glossary/r/reverse_ndr.htm). I first discovered this when our internet connection seemed to be slow but slow because of the amount of traffic being generated. Hope you get to the bottom of it. Please post back when you find the cause (and resolution) so others can benefit. -- Brian Cryer http://www.cryer.co.uk/brian
