Page.User.Identity.Name returns empty string
<p>For some Page.User.Identity.Name always returns an empty string.  Any ideas.  I simply want to print it to the screen.  IIS is set for integrated windows security.</p>

<p>Response.Write("Name = " + Page.User.Identity.Name);</p>

<p>Oops just noticed i hadnt set authentication to windows auth.  Silly me</p>
