I have set up the DNS and DHCP options to enable my clients to automatically detect proxy settings by using the wpad.dat file on my ISA server. I have also managed to set exclusions where needed and it all works perfectly for any client that is already a member of my domain.
We have recently implemented a complete wireless solution throughout our entire organisation which also includes a guest account. Thsi guest account only gives access to the internet via our proxy/ISA server. What I am trying to do is to allow non domain clients to be able to automatically detect proxy settings to allow them to access the internet throught the guest wireless lan. It does not work and I am fairly sure that this is because the wpad.dat fileonly points to the server via it's name and not it's FQDN i.e WEB01 and not WEB01.domain.co.uk. If I type http://web01.domain.co.uk/wpad.dat
on a client connected to the guest network but not on the domain it finds the file. If I leave off the domain.co.uk bit, it doesn't.
If I download and edit the wpad.dat file the entry is web01 under makeproxies and I am thinking I need it to say web01.domain.co.uk but I can't for the life of me figure out how. Any help would be greatly appreciated.
