  • Error concerning intended use of SSL cert for RDP

    I have a third-party SSL certificate installed in the personal certificate store on my 2003 R2/SP2 server

    It lists 'Server Authentication' as one of the Intended Purposes of the certificate in cert store. If I view the properties in cert store on the server it lists the intended purposes as:
    1.3.6.1.4.1.6449.1.2.1.3.4
    1.3.6.1.4.1.311.10.3.3
    2.16.840.1.113730.4.1

    I selected this certificate to be used under Terminal Services Configuration and set the Security layer to SSL and Encryption Level to High

    However I keep getting an error on the RDP client when I connect that 'The certificate is not valid for this usage'

    If I click on View Certificate from this screen is says the certificate is intended for the following purposes:
    1.3.6.1.4.1.6449.1.2.1.3.4

    What am I doing wrong?

      Not sure I really understand the solution to the other posters problem (significance of a non-SGC intermediate certificate)

      The certificate is a Comodo Enterprise SSL

      I found some info here:

      Would a certification authority give a new root the same name as a previous intermediate certificate?

      Unfortunately, some, such as Comodo and GoDaddy, already have.
      Do I need a new cert then?

        Hi,

        Please contact Comodo support.
        Usually I work only with Entrust or Versign certificates and this save a lot of head deck
        (even if it cost more, it cost less in the end )

          Comodo reissued my cert with a single root + intermediate, and its now working for RDP with no errors.
