Setting up a KMS server

  • Server 2008 R2
  • “Windows Server 2008 R2 Std/Ent KMS B” key

Installation process

  1. Load up a VM or physical machines using the “Windows Server 2008 R2 Std/Ent KMS B”.  Click on OK on the warning of using a Key Management Service key
    1. Thats it for installing the service!
    2. I lied, open CMD as an admin, run “slmgr.vbs /ato”. Now your done!

Testing KMS config

  1. Open CMD as an admin and type “nslookup -type=srv _vlmcs._tcp”
  2. Apologize for the censorship on the pic below, security first!

Querying KMS server

  1. Open CMD as an admin and type “cscript slmgr.vbs /dli”


 

Notes:

  • Looking through your licensing agreement there is a difference between KMS A, B and C license keys.
    • A is for Server 2008 Web Edition and for activating other class A servers along with Windows 7 machines.
    • B is for Server 2008 Ent/Std Editions and for activating other class B & A servers along with Windows 7 machines.
    • C is for Server 2008 Data Center and for activating other class C, B, & A servers along with Windows 7 machines.
  • In order for the server to start activating others machines, you must have 5 servers or 25 Windows 7/Vista computers.
  • VMs do not count as unique physical computers however do function as KMS clients.
  • KMS listens on port 1688 to change the port type in “slmgr.vbs /SPrt <port #>”, then “net stop slsvc && net start slscv”
