KMS server redundancy and migration

People,

I've got physical KMS server running on Windows Server 2012, what if the server is failed and cannot be brought up during the software updates ? does my whole Windows OS becoming inactive / not activated ?

Is there any way to provide some sort of redundancy for the KMS server ?

Thanks.



The way KMS activation works is that every 180 days the client must authenticate with the server to remain activated. By default it will try every 7 days.. You can have several kms servers and they don't have to be on 'SERVER' s

ok, so in this case I only have one physical server running as KMS, can I set one more on the existing WSUS VM ?

if for some reason the KMS primary server is down for more than 7 days, what happened to the Tier-1 business servers like Exchange, SQL and SharePoint servers OS (Win 2008 R2 and 2012 R2) ?



Notrhing will happen for 170+ days they will remain activated. A client machine can be a kms server About all you need to do is change the AD/DNS records.



Ah that sounds simple. So no need to provide high redundancy on this KMS server.

Thanks,
