  • Can't connect from Vista to Longhorn

    Hi,
    I'm a newbie with longhorn and have recently installed it. I am now trying to connect to it via RDP from my vista workstation.
    I have tried using remote programs, TS web access but they all end up using mstsc in order to connect to the server and fail.
    The failure message is:
    "The authentication certificate received from the remote computer is not valid or expired".

    I have the terminal services role installed, and the event viewer says a new certificate has been created.

    Why does RDP keep failing to connect?

    by the way - I can connect from longhorn to vista, and from xp to longhorn but not from vista to longhorn....

    Does Longhorn have a firewall enabled by default?
    1 1 was a racehorse.
    2 2 was 1 2.
    1 1 1 1 race 1 day,

      This error can occur due:

      1. http://support.microsoft.com/kb/822406

      2. The client doesnt trust the root CA that create the certificate for the server.

        I've managed to solve the problem by installing an "active directory certificate server" role on the LH server and then took its certificate and installed it on my Vista machine.

        Is this the right way to solve this issue? Do I always need to install a certificate to connect to longhorn using RDP 6.0?


        By the way - setting the mstsc to "always connect" (even when authentication fails) didn't seem to have any effect...
