      • Note: Use a key that’s compatible with your environment. The example above is a key for Win7 Enterprise. For more information on the keys to use, go to Microsoft’s support page.
    • slmgr /ato

Method 2: Use a MAK product key

If there is no KMS server available, you can use the MAK key instead.

  1. Launch Command prompt as an administrator and enter this command:
    • slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (enter your MAK product key after ipk)
  2. Hit Enter and wait for the command to take effect.

Method 3: Configure a KMS host server

KMS activation errors often occur because there is no valid KMS server for your clients to activate against. In this case, you need to install and activate a KMS server. Once you’ve set up a computer to host the KMS software, you can go ahead and publish the Domain Name System (DNS) settings.

For detailed information on the steps to follow, you can check out the following Microsoft support pages:

Method 4: Create a KMS SRV record in MS DNS server

Here’s what you can do if your client cannot locate a KMS host on the network:

  • Verify that your the KMS host is installed and has been activated with a KMS key registered in DNS.
  • Verify the registry to make sure the KMS host server is registering with DNS.

For a step-by-step guide, go to Microsoft’s support page.

Additionally, you can also assign a KMS server manually. If this action didn’t help, you can automatically publish KMS in multiple DNS domains.
