I've installed the SCOM agents manually on each of the non-domain Windows Server 2012 boxes and completed the first step in the article above which was to import the certificate via mmc. I believe the second part of that document was written for Windows 2003/2008 as I cannot locate the add Stand-alone snap-in account. Does anyone have documentation on how to complete this task for Windows Server 2012 non-domain workgroup machines?
