I should probably add that the only two ways I know of making snort into an
IPS;
is by either using snort-inline, which would require IPTables (and this is a
windows question) or
using "flex response" (not sure if this comes with the windows version of
snort), the downfall of flex response
is that is just sends an RST packet to break the connection (this however
does not stop the attacker from re-connecting)
also, you would have to write your own rules such as:
alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS 80 (msg:"WEB-IIS CodeRed v2
root.exe access"; flags: A+; uricontent:"scripts/root.exe?";
nocase;resp:rst_snd;)
(you can see the rst_snd at the end)
but, as "shrek-m" and I (in my earlier email) said, snort cannot really be
used as a firewall.

From what I've read, a couple people have tried, but most people were of
the opinion to use Snort as an IDS, and have a separate firewall.
bingo.
If anyone has done it, do you recommend it? Why/why not?
For those who are against using it as a firewall, again, why?
"snort" iirc is a ids/ips and no firewall
http://www.snort.org/
eg. "iptables" iirc is a firewall and no ids/ips
http://iptables.org/
