<p>I have a problem with a little .Net web application which uses the Amazon webservice. With the integrated Visual Studio web server everything works fine. But after deploying it to the IIS on the same computer i get the following error message:</p>

<pre><code>Ein Verbindungsversuch ist fehlgeschlagen, da die Gegenstelle nach
einer bestimmten Zeitspanne nicht ordnungsgemäß reagiert hat, oder
die hergestellte Verbindung war fehlerhaft, da der verbundene Host
nicht reagiert hat 192.168.123.254:8080
</code></pre>

<p>Which roughly translates to "cant connect to 192.168.123.254:8080"</p>

<p>The computer is part of an Active Directory. The AD-Server was installed on a network which uses 192.168.123.254 as a proxy. Now it is not reachable and should not be used.</p>

<p><strong>How do I prevent the IIS from using a proxy?</strong></p>

<p>I think it has something to do with policy settings for the Internet Explorer. An "old" AD user has this setting, but a newly created user does not. I checked all the group policy settings and nowhere is a proxy defined.</p>

<p>The web server is running in the context of the anonymous internet user account on the local computer. Do local users get settings from the AD? If so how can I change that setting, if I cant login as this user?</p>

<p>What can I do, where else i could check?</p>
