Proxy script issue - Unable to access Internet RRS feed

  • Question

  • Hi,

    I have recently installed a new laptop for a new user. The strange thing is I am able to access internet using IE and chrome without any issues on a broadband network (provided by local ISP). When I am trying to access internet on corporate network using a 'use automatic configuration script' settings enabled with .pac file, I am not able access internet with IE. But in the same network, I am able to access internet using Chrome (Chrome uses IE proxy settings to connect to the internet).

    In IE I am able to access local intranet websites. Only internet sites I m not able to access. Following troubleshooting was done.

    OS: Windows 7 64 bit Professional

    Lap"font-size:0.75em;line-height:1.5;">Internet Explorer : 8, 9 and 10 (tried all versions)

    Proxy settings : use automatic configuration script (http://myproxyserver/region/company.com:xxxx/company.pac file) 

    (BTW, if i mention a proxy server address and port (10.x.x.x:8080), IE works just fine and able to access internet)

    Tried netsh commands, resetting IE, wpad override, IE version changes, no-addons, clean boot, av disable, admin profile, user profile.

    Looking forward to your suggestions.

     Thanks

  • I am able to access internet sites in chrome with same proxy script settings of IE.

      It could be, that chrome is less strict for this situation (e.g. if the specified port is invalid)?
    If I mention the proxy server address:8080 as port and disable use automatic configuration script. I am able to access internet sites.

      ok, this suggests that the proxy directive within your PACfile is valid, but the issue could be with how you are specifying the PACfile within the browser.

    Using proxy script, in IE it works for local intranet sites. Only thing is not able to access internet sites.

    ok, this can be the result if the PACfile is being ignored.

  • http://myproxyserver/region/company.com:xxxx/company.pac

    This doesn't seem to be a valid URL ?

    ( did you mean - http://myproxyserver.region.company.com:xxxx/company.pac )

    have you validated your PACfile to confirm your jscript is ok? (search for pactester or pacparser ?

    or you can try the IP address of your host, to eliminate your DNS records for the host:
    e.g.: http://10.x.x.x:xxxx/company.pac

    Actually, is your PACfile host itself offering the PACfile on your custom port or on port 80 ?
    e.g.: http://10.x.x.x/company.pac

  • Sorry.. Typo.

    Yes. I have checked the pac file and its good.

    I am able to access internet sites in chrome with same proxy script settings of IE. If I mention the proxy server address:8080 as port and disable use automatic configuration script. I am able to access internet sites.

    Using proxy script, in IE it works for local intranet sites. Only thing is not able to access internet sites.

    I am downloading all the security patches for Win 7 and IE. will see the result and let u know.

    Thanks
