Windows 2012 R2 CA and Windows 2003 RRS feed

  • Question

  • Hi Guys,

    Hope someone can help me with this and I am in the correct forum.

    I have and exchange 2003 server (on Windows 2003 server) and windows 2012 R2 CA. (Cannot upgrade Exchange server.)

    I want to setup Client based Authentication for Active Sync, Certificate mapping.

    The issue I am seeing at the moment is that the Windows 2003 machine is rejecting the CA and Subordinate CA certificates.

    "This certificate ahs an nonvalid digital signature"

    I have read that you need a hotfix for this which I have installed and also the CA should be Alternatesignaturealgorithm=0 which was set when I installed it. Yet I still get the problem.

    Anyone know a possible fix for this or have any ideas?

    Thanks for your help

    Craig

  • Hi

    This was to due with Windows 2003 certificate server and version. 

    Basically its better to keep all your server up to date.
