Is there a way to configure AutoDiscovery on a port other 80 and NOT use DHCP (Option 252)? (That is, how can I direct Internet Explorer to ask for wpad.dat on a port other than 80 but not use the DHCP option 252?) I can't get the DHCP thing to work -- apparently because regular users do not have rights to issue DHCP queries (?) This is becoming a huge stumbling block. I want roaming users to be able to log on different AD sites and not have to manually change the IE network configuration, but port 80 on the ISA box is used by IIS and cannot give that up -- want to publish AutoDiscovery on an alternate port.
