Error Code: 502 Proxy Error.

[Mike]

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
