Gustav1908, your question will probably be served best by someone in the Vista Beta Networking forum on the Technet site.

The MSDN forums are oftentimes geared towards developer questions. This forum, in particular, is focused solely on Quality of Service technologies. Here's the link to the networking forum. http://forums.microsoft.com/TechNet/ShowForum.aspx?ForumID=716&SiteID=17

Thanks for using the forums.
