Well, there is an <a href="http://support.microsoft.com/kb/973062" rel="ugc nofollow">older Microsoft Knowledgebase article</a> that describes the situation you are experiencing, except it's for Windows 2008, not Windows 2008 R2.<br />
<br />
That said, I also found a<a href="http://stealthpuppy.com/terminal-server/windows-server-2008-r2-sp1-whats-in-it-for-remote-desktop-session-host/" rel="ugc"> blog that indicates that this fix</a> was also included in Windows 2008 R2 SP1.<br />
<br />
I suppose that leads me to the question: Do you already have SP1 installed on your Windows 2008 R2 server?
