We have a 2008 R2 server running VAMT 3.1 and with KB2757817 installed. I added our Windows Server 2012 and Windows 2012 R2 KMS product keys to the KMS host as well as our Windows 8.1 KMS key, and restarted the system.
So that when I look at the list of Product Keys I see the following keys:
Windows Server 2012 RTM ServerDataCenter;ServerStandard;ServerMultiPointStandard;ServerMultiPointPremium Volume:CSVLK
Win 8.1 RTM Enterprise;EnterpriseN;Professional;ProfessionalN Volume:CSVLK
Windows Server 2012 R2 RTM ServerDataCenter;ServerStandard Volume:CSVLK
Windows Server 2008 R2 RTM Std and Ent Volume:CSVLK (KMS_B)
Windows 7 All Volume Editions Volume:CSVLK
I then go to one of our Windows 8.1 systems and run the following commands:
cscript c:\windows\system32\slmgr.vbs /skms <servername>
cscript C:\windows\system32\slmgr.vbs /ato
and I get the following error message:
"Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information."
Meanwhile Windows 7 clients still activate without a problem.
On the KMS host I run slmgr /dlv and get the following:
Name: Windows Server(R), ServerStandard edition
Description: Windows Operating System - Windows Server(R), VOLUME_KMS_R2_B channel

I've seen in other articles that the description should be
"VOLUME_KMS_2012-R2" channel instead of "VOLUME_KMS_R2_B channel"
My question is how do I get the 2008 R2 KMS host to activate Windows 8.1 clients?
Did I miss a step in adding the 2012 R2 KMS key, and if I did what step did I miss?
