Proxy Auto Configuration from DHCP

Posted on 2009-05-05

I need to configure proxy setting on domain clients using the DHCP server, our proxy is a blue coat appliance.

I have created the a wpad.dat file and host it on a web server, and maped the dhcp to that url. but clients didnt take the setting. even I have put the dat file locally on one client and configure the client to read proxy setting locally from that file but it didnt work.

I have taken and check the content of the dat file and its seems fine .

can any one help me with a step by step procedure to do it and troubleshoot this issue?

i assume you're referring to setting a Microsoft  DHCP .
this technet covers the info , i assume you followed that:

did you actually check that the client is configured to "automatically detect settings" ?
that small checkbox is causing much troubleshooting in WPAD issues :)

good luck

I suggest you use the DNS-method instead of DHCP.
The DNS-based method is easier.
I totally documented it there:

hope it helps

if your users cant access the wpad file then it will not work.... make sure the http://server/wpad.dat is accessible. first.
check permissions etc..

no you dont , you just configure the IE to "automaticly detect settings" and you should monitor your proxy to indeed see that it is using it to access external websites..
