How to Activate Server Core

Just because you”re running Server Core doesn”t mean you can get around Activation. No more going to the Start Menu -> Programs option. In Server Core you can Activate the server in two ways, one locally and the other remotely. Both ways use the Software Licensing Management Tool (Slmgr.vbs)

Local Method:

At the command prompt type: Slmgr.vbs –ato

Remote Method:

Cscript windowssystem32slmgr.vbsServerName UserName password:-ato

    Hmm, very cognitive post.
    Is this theme good unough for the Digg?

    But… how do you enter your activation number?, because running the command if you have installed the server by default, the install process enters a dummy activation number, and this one will offcourse not work for activation. How do you enter your own activation number?

  3. Robert says:

    before running Slmgr.vbs –ato
    run Slmgr.vbs –ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX (Replace the Xs with oyur numbers)
    Then you can activate
