Description

When behind a corporate firewall, the online help features do not work with the new help system and .net 2.0

I kept getting a 407 error - proxy authentication required.

After much research online, I stumbled upon a MS document describing how to fix the issue.

http://support.microsoft.com/kb/910804

You receive a "Proxy authentication required" error message when you try to use Visual Studio 2005 online features

Solution used:

Method 1: Modify the Visual Studio 2005 configuration file

Steps to Reproduce:

Solution to issue. (May want to add it to the local help since it fixes the online help problem)

1)

Browse to "\Program Files\Common Files\Microsoft Shared\Help 8\"

2)

Open dexplore.exe.config

3)

Add the following defaultProxy text (REPLACING MYPROXY.COM with YOURS) in the space indicated. You may be using a different port as well.

    <system.net>
        <settings>
            <ipv6 enabled="true" />
        </settings>

        <defaultProxy enabled="true" useDefaultCredentials="true">
            <proxy bypassonlocal="True" proxyaddress="http://MYPROXY.com:80"/>
        </defaultProxy>

    </system.net>

4)

Save the file.

5)

Restart dexplore (You may need to kill all copies of it first).

NOTE:

After further research and testing (My company loves to change the proxy server), I was able to get it to use the auto proxy detection in.Net 2.0 by doing the following instead of specifying a static proxy:

        <defaultProxy enabled="true" useDefaultCredentials="true">
        </defaultProxy>

However, automatic detection will be slower than the direct to server method.
