Okay, I guess that answers the first question, thank you.

Netmon and Snort share only one thing - the ability to grab packets off the 
wire.
Other than that, they're nothing alike.

You can no more use Snort for traffic analysis than you can Netmon for traffic 
alerting and blocking.

Yes, they are different, but yet similar in other ways, which is why I was 
looking at that one first.  Both of them monitor network traffic, but Snort has 
those signature files which throw away all packets of known origin, and alerts 
you to the suspect ones.  Looking at Network Monitor, I see it supports capture 
filters which I got me wondering if it could be used as a suitable replacement.

Basically, I was looking for something that I can fire up whenever there is a 
lot of traffic on the network to see if someone brought in an infested home 
computer and put it on our Intranet.  If it is something like Network Monitor, 
I won't have to dedicate an entire server (or two) just to run it and spend 
hours configuring it to work.

What do you want; a Snort replacement of a network traffic analysis tool like 
Netmon (they're different beasts)?
TMG can replace Snort as an IDS, except that you don't' have access to the GAPA 
signature language.

This is a bit off-topic, but I figured that if anyone would know it would be 
you guys...

I'm trying to find a suitable Windows-Based replacement for programs like 
Snort, as I get really-really sick of digging through tons of propaganda on 
configuration files to get a program working.  Looking at the program a bit, it 
seems like I should be able to do something similar to Snort with a basic 
program such as Network Monitor, but I haven't worked with the filters enough 
to be able to tell if I can do that or not.

So, two questions:
1. Can the functionality of Snort be done with Network Monitor?
2. What is the best Windows-Based program for doing IDS monitoring? (freeware 
preferably)
