BEWARE: Couple of issues after Upgrading a CM12 Primary site to Windows Server 2012 R2

After upgrading your CM12 Primary site(s) to Windows Server 2012 R2, you may experience the following issues.

1.  You may not be able to access the console after the upgrade.  Check SMS Admins permission to the Primary site's WMI's root/SMS and root/SMS/Site_XXX.

SMS Admins group should have the following:

• • Root/SMS
    • Enable Account
    • Remote Enable
  • Root/SMS/Site_XXX
    • Executable Methods
    • Provider Write
    • Enable Account
    • Remote Enable

2.  Your MPs may experience issues moving files to its Primary site’s inbox folders after upgrading your Primary site to Server12 R2.   Overtime, if this is unnoticed, you would see your clients become inactive in the console.   You may see similar errors below in your MPFDM.log.

The only fix we have found so far that’s effective is to add the MPs in local\admins group of that Primary site that’s been upgraded.
