I undeed all the steps and reinstalled termsrv.dll build 2180. TermServer started working again, the Remote tab reappeared and Fast User Switching worked again.
I then used Sala's installer. For some reason I also had to fix this problem: [url="http://support.microsoft.com/default.aspx?scid=kb;en-us;323497&"]http://support.microsoft.com/default.aspx?...b;en-us;323497&[/url].
Anyway everything's working now.
