A while back I came across a way to get DCM to look in to a computers certificate store so as to evaluate some criteria on the certificates and produce a compliant\non-compliant state. I finally got around to making a short movie on how to get this done, as well as introducing a way to auto-remediate clients with invalid certificates.
This is by no means suppose to be a complete KB977203 certificate find and fix solution, because you cannot get at all the clients. DCM is unable to get to the 32-bit CAPICOM DLL when the client is running in a 64-bit OS due to WOW .
Depending on your environment this could exclude 5% or 95% of your clients. I really only use KB977203 to spice up showing DCM running a script to evaluate for compliance with auto-remediation tacked on the end.
I made this with Camtasia from TechSmith, actually been fun using it, still a novice so please do excuse my butchery of the timeline, my liberal cropping of user interface delays and near obsession with the zoom and pan feature ;-)
