I haven't reinstalled ISA as of yet. When I couldn't get any of my internal
clients to access the internet I determined it to be because DNS wasn't
resolving which led me to think DNS wasn't configured correctly. So I've
since then uninstalled ISA and trying to get my DNS working correctly.
Now.
When I connect to my linksys router using the default method with my AD
Integrated zone I'm able to resolve external resources without any problems.
When I disconnect from the router and connect the external nic to the dsl
modem, change the gateway of the internal nic, establish a connection to the
internet and try to resolve external resources I run into problems.

I think that there is an entry in the DNS server that you've missed.
Here is what I understand:
When you don't have the ISA in front of your DNS server can resolve host
names.
When you put ISA in front of it your DNS server cannot resolve host names.
Let's forget workstations for a minute because if the DNS server can't
resolve names then you won't get anywhere. Is the DNS server AD-integrated
or not?

Yes the gateway's blank and I get the same errors when I attempt to nslookup
from a workstation who's gateway is that of the router. I know I'm missing
something but I'm not seeing it because it resolves fine when connected to
the linksys.
Thanks

Marvin,
Is the gateway of the internal interface literally 0.0.0.0? If so, change it
to blank, not zeros.
On the external interface add the addresses of your ISP's DNS servers.
How far are you getting? It doesn't sound like your forwarders are working
at all. What happens if you ping the external nic address from a
workstation?
