Hi I work for a school and we are about to roll out a heap of laptops for kids. They will be bringing their laptops to school and taking them home so we are trying to get them to "just work" when they bring them to and from school. To do this we have set up DNS and IIS 6.0 to server out a wpad.dat file while they are at school so all their connections will go through the school ISA 2006 proxy and when they are at home because the proxy can not be found it will automatically connect them locally to their home set up.
Internet Explorer 8 is set to automatically detect settings but for some reason it is not applying the wpad.dat settings and trying to connect to website without going through the proxy. If we set Internet Explorer 8 to use an automatic configuration script using the wpad.dat it works fine and Internet Explorer 8 can connect to sites through the proxy. Firefox and Internet Explorer 6 are also set to automatically detect settings and both of them are working.
We are testing on 4 machines 3 are running Windows 7 Enterprise 32bit and the other is Windows Server 2003 which has IE6 on it, all machines are part of the same domain.
I have tried doing the sets here http://technet.microsoft.com/en-us/library/cc302643.aspx#DNSIssues as well as a few others sites suggestions.
Out wpad.dat file looks like this
function FindProxyForURL(url, host)
return "PROXY ourproxyservername.domain.name.:8080";
Any help would be great.

Thank you for the post.
According the description, this issue is related to windows 7(automatically detect settings not working on IE8 Win7). In general, when "automatically detect settings" is selected, IE will query using DHCP. It will then go to DNS to get the WPAD location if DHCP fails. Finally IE will send HTTP request to download the WPAD file. So it is good for you to make a tracer to see what happened.
I also did some research and find the following issues for IE8 on win 7.
Meanwhile, you may you contact Microsoft Product Support Services via telephone so that a dedicated Support Professional can assist with this request.

viernes, 28 de mayo de 2010 14:04Thanks for the reply. The problem has been resolved. They guy in charge originally set up wpad.dat to use DHCP and then changed to using DNS and wpad.dat was still partially configured with DHCP and so the correct wpad.dat was not getting to the client because DHCP was sending it out first. Correcting the DHCP options to allow wpad.dat to be sent only by DNS fixed the problem.
