    Crazy IE wpad issues

    Morning All, got a bit of a strange one here but I hope someone can help. We have a wpad.dat setup and deployed successfully which defines some local proxy exceptions for sites which we have hosted locally on the LAN. This has worked for months with no problems (and is still working today!). However, I edited the wpad.dat file yesterday to add another exception (for a new site we are setting up) and IE is still trying to go through the Proxy to get to it. I have followed the instructions at Troubleshooting Automatic Detection to force a refresh of the file but it isnt playing a ball. To make things even more confusing, I have Google chrome setup to use the Proxy settings from IE (therefore use the same wpad) and it has picked up the new exception! Does anyone know of a hack I can use to force this to refresh in IE? I have this WPAD in use on the whole network so using Google Chrome just isnt an option unfortunately

    any help would be hugely appreciated.

    IE like to cache proxy.pac (and, by extension, wpad.dat) - How to disable automatic proxy caching in Internet Explorer might help.

    Thanks for the help Tom, unfortunately I already have that GPO set in my Default domain Policy so its a no go. I do have some more info though! It seems that IE has picked up the new settings on my servers and on almost all domain PCs, its just my PC and the other Technicians! The only difference I can think of is that we have 64bit Win7!? its very strange but I will continue to fiddle with it and see where it gets me!

    Could possibly be your IE8 browser - Delete your temp,history etc using the Delete button under Internet Options\Browsing History and make sure that Preserve Favourites Website Data is unchecked.

    Hi

    Are the any filters on the GPO?
    Have you run the GPO force?
    Are your PC's identical as the other PC's (except 64bit)?

    Regards
    Sukh
