2020-10-16T09:40:37.22+00:00

I got a task to decommission a VAMT server, but my manager said KMS is at other machine to we can disable VAMT server. I read some article at MS portal, it stated that we use "Volume Activation Services" Role to configure KMS server. What I understand, if we install "Volume Activation Services" , server will be configured VAMT role as well.

1. What is VAMT and KMS
2. What is difference between VAMT and KMS
3. Can we install VAMT and KMS role at different-different machines

   Thanks for your answer.

   1. VAMT needs SQL DB for installation, so if I configure a VAMT machine. How my VAMT will know that which is my KMS server because what I understand now VAMT is just a tool like RSAT. In RSAT, We need to just simply install and open the required tools for example "Active Directory Users and Computers" and it automatically connects to same site DC. So how my VAMT will connect to KMS server?
