Thanks T&E,
Wish I had the luxury of time to research SCCM more.
If I had my choice, the whole thing would be torn down and re-started from scratch, but alas, like most things in IT, we need this fixed yesterday.
Our main issue is getting SCEP installed and managed for all Servers, Workstations and Laptops.
After researching and troubleshooting the issue to death for some time now, it seems Server 2012 R2 is not supported by our current SCCM version.
Deploying and managing SCEP is the only thing our SCCM has been setup to do, so an upgrade looks like the only option.
If anyone knows different, I'm all ears.
Once this is fixed, the plan is to dive deeply into anyweb's guides and anything else I can find on SCCM. I've learned a ton already.
Thanks again.
