Wireshark is very good for a free tool ________________________________ From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Berny Stapleton Sent: Thursday, November 01, 2007 7:01 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: Network/Internet Monitoring Network Monitor, it's available here: http://www.microsoft.com/downloads/details.aspx?familyid=18b1d59d-f4d8-4 213-8d17-2f6dde7d7aac&displaylang=en Most of the ethereal developers left ethereal and "forked" the project, but ethereal is no longer under active development. Details here: http://www.wireshark.org/faq.html#q1.2 Basically, get Wireshark, it's the updated version of ethereal. A company I do work for has WinPcap in their standard build, and they test everything extensively, so I wouldn't be too worried about it; especially in an SBS situation. If you are that worried get Network Monitor, it's supported by Microsoft in case you have any major problems. My personal preference would be Wireshark as it seems to have more protocol decodes, if all you are after is to see top talkers though, either will do the trick. Berny On 01/11/2007, Timothy R.

Also Microsoft has a free tool, I think called "Microsoft Monitor".

I'd load it on a laptop, and then plug a hub between the Ethernet jack and the server, and add the laptop to that hub. Fire up ethereal, and let it start capturing packets. It will give you a nice picture of what protocols are being used first, and then can analyze based on source, destination, etc...

Does anyone know of a free (or one that offers a demo) utility that I can use relatively fast to see what /or who is generating all this traffic?
