&lt;p&gt;It finally explains nicely how this hell works on Windows and why Win2K8 behave correctly while Win3K does not in my configuration !&lt;/p&gt;
&lt;p&gt;Thanks again for taking time writing this stuf !&lt;/p&gt;
&lt;p&gt;Would like to see the same stuf for IIS6/7 : what source IP it does use for outbound connections and in which case ?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=3278880" width="1" height="1"&gt;</description></item><item><title>re: Source IP address selection on a Multi-Homed Windows Computer</title><link>http://blogs.technet.com/b/networking/archive/2009/04/25/source-ip-address-selection-on-a-multi-homed-windows-computer.aspx#3277245</link><pubDate>Thu, 27 Aug 2009 01:17:32 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:3277245</guid><dc:creator>web tasarim</dc:creator><description>&lt;p&gt;on this matter Thank you for sharing with us such a thing&lt;/p&gt;

&lt;p&gt;When the calling application binds to the VIP as its prefered source IP are you saying that the traffic will look for routes only applicable for the interface the VIP is bound to? That would suggest that the trafic will blackhole as there will be no logical route off of the server for this interface&lt;/p&gt;
&lt;p&gt;Example config&lt;/p&gt;
&lt;p&gt;Loopback Ethernet adapter1&lt;/p&gt;
&lt;p&gt; &amp;nbsp; IP Address. . . . . . . . . . . . : 10.173.48.58&lt;/p&gt;
&lt;p&gt;Ethernet adapter2&lt;/p&gt;
&lt;p&gt; &amp;nbsp; IP Address. . . . . . . . . . . . : 10.171.34.107&lt;/p&gt;
&lt;p&gt; &amp;nbsp; Default Gateway . . . . . . . . . : 10.171.34.97&lt;/p&gt;
&lt;p&gt;Ethernet adapter3&lt;/p&gt;
&lt;p&gt; &amp;nbsp; IP Address. . . . . . . . . . . . : 10.171.33.107&lt;/p&gt;
&lt;p&gt; &amp;nbsp; Default Gateway . . . . . . . . . : 10.171.33.97&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=3241678" width="1" height="1"&gt;</description></item><item><title>re: Source IP address selection on a Multi-Homed Windows Computer</title><link>http://blogs.technet.com/b/networking/archive/2009/04/25/source-ip-address-selection-on-a-multi-homed-windows-computer.aspx#3239795</link><pubDate>Tue, 12 May 2009 17:28:21 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:3239795</guid><dc:creator>Damian Crosby</dc:creator><description>&lt;p&gt;What would happen if you had a loopback adapter installed that had another IP assigned to it and you were to use that IP as the source. For example a /32 address assigned to the loopback that was being advertised out of both interfaces using RIP to provide resiliancy using networking protocols.&lt;/p&gt;
&lt;p&gt;Example: &lt;/p&gt;
&lt;p&gt;Source supplied in the call:10.0.0.10 &lt;/p&gt;

&lt;p&gt;Nic 1 - 192.168.1.10/32 &lt;/p&gt;
