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.
