We have a problem with web proxy settings at the moment, and have done for some time. The story so far: We have an ISA server in which the settings were pushed out via logon scripts. Now we have GPO's set up that push the settings out via GPO. This works great, except for a few exceptions. Since I have been here (18 months) we have had sporadic issues with a rogue proxy setting appearing for specific individuals. IE, user one will log on and have the rogue setting of 'julius', we will 'gpupdate /force' and the right proxy settings will appear, until the user turns off his pc and comes in the following morning to find the same issue. Out of a user base of around 200 pc's this issue is currently happening to two users. We do have a legacy server called 'julius', which did have a free proxy program on it at some point, but in the services the only entry I can find is 'WinHTTP Web Proxy Auto-Discovery Service.' which is described as... This service is disabled, but by it's description I'm not sure that will help. I have also restarted the server a few times over the months to see if there is something running that shouldn't be, checked MSconfig/services and startup, but can't find anything there that shouldn't be. Turning the server off isn't an option at the moment unfortunately. Does anyone have any ideas on how to try and stop this other than trying a complete turnoff of the server? Many thanks in advance guys.
