COM+ Network Access firewall exception for WS2012r2

Say you have a shiny new Windows Server 2012 r2 that you want to view the event logs on from your Windows 8.1 workstation (why am I saying this… no reason).

If you have Windows Firewall turned on (in my case, through a Group Policy Object linked to the OU with all our servers) you probably are out of luck even if you have remote administration enabled for your existing WS2003, WS2008 and WS2008r2 boxes

So, you launch Group Policy Management console (gpmc.mmc) from your Windows 8.1 workstation, and drill down… (Computer configuration\Policies\Windows Settings\Security Settings\Windows Firewall with Advanced Security).  Inbound rules, click for New Rule, use predefined – but, hey! where’s my COM+ Network Access (DCOM-In)

What gives?  Ok, I’ll play – what if I run Group Policy Management Console from my new WS2012R2 box?

Well – it’s there.  WTF Microsoft?  I spun up a clean Windows 8.1 Enterprise VM, downloaded RSAT for Windows 8.1 x64 from Microsoft again – same deal.  Windows 8.1 is lacking the COM+ firewall predefined rules. 

Oh well, I’ve got my GPO updated now so I don’t care enough to open a MSFT ticket!
