title: Install Microsoft KB951608 with WIX
body: <p>On our server (win 2008 r2) we enabled the setting "force network authentication" to enforce that the client must support the NLA, because the port 3389 is directly reachable from the internet. But on Windows XP SP3 the NLA seems to be disabled per default. As I wrote an installer with WIX to distribute the rdp files, I'd also like to install these two registry-entries (one is a comma separated list of type REG_SZ and one is a list of type REG_MULTI_SZ) as descriped in <a href="http://support.microsoft.com/kb/951608" rel="nofollow noreferrer">http://support.microsoft.com/kb/951608</a>. </p>
  
  <p>I've already tried it with RegistrySearch and RegistryValue, but I haven't succeded. The main difficulty is how I should handle these comma separated list of type REG_SZ.</p>
  
  <p>Can anyone give me a hint? Thanks in advance.</p>
