    Users get the following error when trying to access a web page on one of our
    servers.
    Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform
    Resource Locator (URL). (12202)
    The server has an address on a 10.25.0.0 subnet.
    There is a DNS A record for the server.
    Most users have IE6 SP2.
    An ISA server is configured in LAN Settings.
    In LAN Settings - Advanced, I have created an Exception as 10.25.*.*
    Therefore, with the exception, I don't understand is why IE is trying to go
    through the ISA anyway.
    If 'Automatically detect settings' is checked, users get the web page. I
    don't want to check this.
    I have no issues with any other intranet pages.
    If someone can explain this, it would be appreciated.

    Regards,

    Mike.

    I think you should be asking your server operator.
    After all, it is where the error message originates.
    Otherwise trace it, e.g. with WireShark.


    Good luck
