  • Can RDP from 2003 but not Win7 to 2008 Terminal Server

    Hi,
    Got a strange issue with 3 of our terminal server hosts all running Windows 2008. If I attempt connection from my Windows 7 pc an error message "your credentials did not work" pops up and I can go no further. If however I RDP onto a 2003 Terminal server using same domain credentials all is well. I can then daisy chain from my Windows 7 pc to Windows 2003 server and from there rdp successfully to the 2008 server.Reference to Security log gives a Event ID 4625 "An account failed to logon"

    Guess it might be kerberos/certificate problem but not nailed it yet.

    Any ideas

    Thanks in advance.

    Check the option cicled in the attached image. There is a corresponding setting on Server 2008. Can't post an image as my Hyper-V Server is not running at the moment.

      Hi Biggles,
      Thanks for the tip but I had already tried that. As suspected it appears to be a certificate problem. We have 2 subordinate CA's and one appears to be issuing certificates that are flagged "wrong issuer" when runnining certutil on the TS servers. I have pointed the 3 2008 TS servers to the other subordinate and all is now OK. It just remains for me to sort out the chaining on the problem issuing CA so autoenroll will work in the future

      Cheers.

        Might sound daft but have you tried using the full context name for logging in.

        domainname\username

            No worries, we had a similar message so just a different spin.
