I can't seem to get this to work. It may be an IP address
misconfiguration or something else. Here's the setup:
DSL modem with a static external ip address connected directly to a
Dlink router.
Dlink router has an LAN ip of 172.16.1.1 & subnet of 255.255.255.0

Fine,...but you need to keep in mind that you have created a meniacle
Back-to-Back DMZ to deal with between the ISA and the DLink.

ISA 2006 Server which is connected to the LAN port of Dlink router has
the WAN NIC ip address set to 172.16.1.2, gateway is 172.16.1.1 & DNS
set to 192.168.1.253.

Fine,..but you can leave the DNS blank on the external nic.

ISA 2006 Server has LAN NIC (which is connected to a switch) with an
ip address of 192.168.1.1, DNS set to 192.168.1.253 & no gateway
defined.

Fine.

There are about 20 other computers connected to the switch that all
receive 192.168.1.x ip addresses & subnet of 255.255.255.0 & gateway
of 192.168.1.1 & DNS of 192.168.1.253 from our domain controller which
is a DHCP server. Thanks alot in advance.

Fine,...although I would have use a much higher IP range in the third Octet
to avoid the ectrememly heavliy over used "1" subnet. You will never be
able to establish a Site-to-Site VPN or any other private connection to
another network if they use the same range,...which is very likely with such
and over-user range as 192.168.1.*. But it is kinda too late now without
re-addressing the whole LAN.

Anyway,...everything looks fine,...so what doesn't work?????
