Connection to RD Gateway from Windows 8 thru TMG 2010


  • We have RD Gateway on Windows Server 2008 R2 behind TMG2010

    Everything works fine when connecting from Windows 7/XP/2003 clients, but it fails to conenct from WIndows 8/2012

    The error logged on TMG server is:

    12309 The server requires authorization to fulfill the request. Access to the Web server is denied. Contact the server administrator

    Any idea how to fix this?

    No, that wasn't the issue.

    I fixed the issue by adding /remoteDesktopGateway/* to the path mapping on TMG server

    Wired thing is that that folder does not exist on RDG server and is never hit from TMG server.

    Anyways it worked.
