+How can I run Orthanc behind Microsoft IIS?
+===========================================
+
+Similarly to :ref:`Apache <apache>` and :ref:`nginx <nginx>`, Orthanc
+can run behind `Microsoft IIS (Internet Information Services)
+<https://en.wikipedia.org/wiki/Internet_Information_Services>`__
+servers through reverse proxying. The instructions below are provided
+courtesy of `Mark Hodge
+<https://groups.google.com/d/msg/orthanc-users/3-b3cLBAr8U/QIePcADMAAAJ>`__.
+
+- IIS is available as a feature you can enable via the Programs and Features in non Server versions of Windows.
+
+- Add Application Request Routing 3.0.
+
+- Add URL Rewrite module 2.
+
+- In IIS Manager bind an SSL certificate to port 443 on the default web site being used for Orthanc.
+
+- Add the following ``web.config`` at the root of the default website:
+
+.. code-block:: xml
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <configuration>
+      <system.webServer>
+        <rewrite>
+          <rules>
+            <clear />
+            <rule name="HTTP to HTTPS redirect" stopProcessing="true">
+              <match url="(.*)" />
+              <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
+                <add input="{HTTPS}" pattern="off" ignoreCase="true" />
+              </conditions>
+              <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Found" />
+            </rule>
+            <rule name="ReverseProxyInboundRule1" stopProcessing="true">
+              <match url="(.*)" />
+              <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
+              <action type="Rewrite" url="http://127.0.0.1:8042/{R:1}" />
+            </rule>
+          </rules>
+        </rewrite>
+      </system.webServer>
+    </configuration>
+
+- In IIS Manager Open Application Request Routing Cache click on
+  Server Proxy Settings on the right side of the window, change the
+  Time-out to a much higher value. eg., 3600 = 1 hour to ensure
+  download of DICOMDIR or ZIP's doesn't time out.
+
+- To allow user authentication against an Active Directory group add
+  the following directly after ``<configuration>`` in the above
+  ``web.config``, grant the appropriate Active Directory group read
+  permission on the ``wwwroot`` folder:
+ 
+.. code-block:: xml
+
+    <system.web>
+        <authentication mode="Windows" />
+    </system.web>
+
+- You also need to make sure registered users is empty in the Orthanc Configuration.json file:
+
+.. code-block:: json
+
+    [...]
+    "RegisteredUsers" : {  },
+    [...]
