I work in a High School and a number of are teachers use laptops that they log on locally to, this allows them to use them at home, at my pervious job the teachers could come into the school and not have to uncheck the Auto Detect Proxy tab and re enter it every time they want to use the internet. Im sure this has something to so with the WPAD file that sits on the server! Im pretty sure I can find this however I don't want to touch it until I have a better understanding of what each section does! Can anyone help me with this issue?
You need more than just a WPAD - you need to allow autodetect to find it. 2 ways to do this:
1. serve it from wpad.localdomain/wpad.dat - relies upon all these machines having the same domain suffix
2. issue DHCP option 252 with the location of the wpad.dat (or proxy.pac, the 2 are interchangeable)
Just want to clarify something... I want to get the clients on my boarders network to automatically detect the proxy so I have made a proxy.pac which works. I have added the 252 option in DHCP and when obtaining a IP address DHCP added the location of the pac file into the Address box (eg http://servername/proxy.pac) in the automatic configuration bit of IE. But it doesn't work until I tick the "Use automatic Configuration script" tick box, is there a way to get this tick box ticked without manually doing it? Or should this work without this tick box being ticked?
You'll need "automatically detect settings" ticked - but thats usually default (or was last i looked).
Looks like that's working if the machines have up to date IE cheers
