Subject: Firewall solution for Windows 2003 Server

Are you suggesting that the win2003 server will be the point of contact for
the Internet? is this a wise choice or just a product of your setup?

I dont like application layer firewalls, they fill me with dread, yes the
displays are nice , but that doesnt mean it cant be acheived elsewhere.

I would prefer to point you in the direction of Smoothwall, and IPCOP (both
are free) they run on small Pentium boxes , seperate to the win2003 server
and offer excellent protection and performance.  You can even just setup a
nice FreeBSD box with simple ipchains packet filtering if needs be, but
those two suggested would be a nice set in the right direction.

Any ideas on amounts you have to spend? that obviously sways a decision
somewhat, but I still like to stay away from desktop application layer

Hope that helps.

Kind Regards
