No, ya didn't, but I'll answer anyway. ;-) ..that's not "behind" ISA; that' "in front of"... What's in the ISA WEBEXT..log? Does ISA know to use your DNS server for that domain?

My whole ISA setup currently works like a charm for all of the fancy schmancy requests I’ve had from my users. But this latest one baffles me intensely. I have a PIX firewall behind my ISA (LAN → ISA →PIX → Internet), off which I host a DMZ segment to my parent company over a WAN link. My DNS Server is also hosting a secondary DNS to their primary Windows 2000 DNS Servers so that I am able to name lookup their servers etc. I have thus also added their domain name to my "Append these DNS suffixes..." option under TCP/IP DNS properties on my workstation, and any nslookup for a server in their domain works 100%. The problem is though, when I try and connect to ANY of their websites (and there are quite a few) via IE, I can only connect by using the IP Address of the site, and *NOT* the FQDN. As noted, all DNS lookups work fine, (except Reverse Lookups - is that a problem?), and I cannot think of anything else more to try. I have enabled debugging on my PIX to see if there is any traffic, and when using the FQDN the traffic does not even get to my PIX, so that tells me the problem is between my IE and the ISA. Is there perhaps someone who has a similar scenario that may be able to suggest something?
