How To Activate Windows Server

Activating Windows Server

To ensure that your organization is correctly licensed and to receive notices for product updates, you must activate every copy of Windows Server 2012 that you installed which i clear in this post. In Windows Server 2012 there is no longer an activation grace period. A server that is not activated will be in a “notification” state which can result in hourly shut downs until it is activated.
How To Activate Windows Server
Your server is activated using a Product Key. Depending on your licensing agreement and your infrastructure this can be done in a variety of ways, using tools such a Key Management Services (KMS), Volume Activation Management Tool (VAMT), Active Directory Based Activation, and Automatic Virtual Machine Activation (AVMA).

You can check the current state of your server by running the following command:
Slmgr –dlv

If you have installed an evaluation version of Windows Server 2012 R2, you will encounter hourly shutdowns until you run a rearm command:
Slmgr -rearm

View the full range of switch options you can use with slmgr by running the command:
slmgr -?

A full discussion of licensing and activation is beyond the scope of this course. Also, licensing specifics will vary per region and with specific agreements you or your business have with Microsoft.
