&lt;p&gt;.NET Framework 3.0 Feautures -&amp;gt; &lt;/p&gt;
&lt;p&gt;WCF Activation -&amp;gt;&lt;/p&gt;
&lt;p&gt;HTTP Activation&lt;/p&gt;
&lt;p&gt;After that, your config tool worked.&lt;/p&gt;
&lt;p&gt;Still, your comments seem to suggest that the asynchronous handler can also be installed and configured on 2K3 and IIS 6, even if it is not adviseable. All the same, I'd like to know how that configuration could be accomplished on that platform.&lt;/p&gt;
