SYMPTOMS

Consider the following scenario:
  • On a website that hosts a Silverlight application for Microsoft Lync 2010, the default page of the website starts the Silverlight application.
  • You add the website to the trusted sites zone in Internet Explorer.
  • You open the default page by using a Uniform Resource Location (URL) address that does not contain the page name. For example:
    http://hostname
In this scenario, the Silverlight application does not start. However, when you open the default page by using a URL address that contains the page name, the Silverlight application starts successfully. For example:
http://hostname/default.htm

CAUSE

This issue occurs because of a bug in an internal method of the Lync 2010 Client API.  This method checks the trust level of a given URL incorrectly and ignores a URL address that does not contain a page name.
