Hi Tom - good news is the last couple of hours have been smooth once the Use HTTP 1.1 With Proxy Connections has been enabled. Last question - configuring the clients with that through group policy - I've looked through the defaults and it seems like I'm going to have to create an ADM file for that one setting and import that into the group policy manager - am I correct? Thanks for all of your help. -- Robert Thomas W Shinder said: > http://www.ISAserver.org > > Hi Robert, > > While adding a second NIC and putting the ISA firewall in the path will > improve security, it won't solve the issue you have right now with the > Web browsers. > > > Tom > www.isaserver.org/shinder > Tom and Deb Shinder's Configuring ISA Server 2004 > http://tinyurl.com/3xqb7 > MVP -- ISA Firewalls >
