Telnet is not installed. Cannot install it via Windows Features, gives error, maybe because it isn't activated.

Question: What is this activation error?

If I try with the:

Slmgr.vbs /skms kms_server:1688

I got the same error message, maybe a client-side problem?

  • Get putty to bypass telnet, and try to telnet to the kmsserver on port 1688 please

Open up an elevated cmd prompt and enter the following commands to uninstall and reinstall the Product Key:

slmgr –upk 
slmgr –cpky
slmgr –rilc
slmgr –ato

NOTE: Useful commands for SLMGR

-dli -> Display License information

-dly -> Display detailed License Information

-upk -> Uninstall Product key

-ipk $key -> Install Product Key

-ato -> Activate Windows

-rearm -> Reset the Licensing Status of the machine

-cpky -> Clear product key from the registry

-rilc -> Reinstall System License Files

Also, you can open Server Manager -> Local Server -> Click your Product ID and Windows Activation prompt will popup.

However, if you plan to use volume activation, please refer to:

Appendix A: KMS Client Setup Keys


If you run Evaluation Versions, please refer to Evaluation Versions and Upgrade Options for Windows Server 2012.
