Hi I hate to interrupt the very interesting discussion about ISA being part of the domain, but I added the wpad entry in the DNS server and put the FQDN of the isa for that alias as mentioned in the document, I enabled for the Internal network The Auto discovery option (default port 80 because of DNS) and enabled the FW Client support for the internal network, the FW client can't auto detect yet.(if I set the server name it works fine).If I browse to the http://wpad:80/wpad.dat <http://wpad/wpad.dat> at the isa it says page can't be displayed, and the same at the client. What could be the problem now? Also I have a group of users connecting through this ISA2004 and I have another group who connect through ISA2000, the auto detection is still not working now but if it works will it affect the other group of users? The other group have routes to both ISAs but access rules on both ISAs restrict the traffic. thnx r. _____ From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Monday, December 20, 2004 3:00 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: FW Client (ISA2004) http://www.ISAserver.org Hi Ruba, Autodetection depends on wpad entries in DHCP and/or DNS.
