Verify Service And Activation Key Installation |
- Open the operations console and navigate to the Key Management Service folder and State view to check if the service has been discovered and is in good state.
- If the state is not good, use the Health Explorer to identify the issue.

Service Lacks Access To DNS Server |
- Open the Operations console, click the Monitoring button, open the Key Management Service folder, and then open Alerts view to determine if there are any ‘DNS RR Publishing Failed’ alerts related to that service.
- If the mentioned alert exists, grant the KMS server the relevant permission to DNS server and you can also verify the DNS server is accessible from the KMS host.
- After the KMS service completes DNS publishing, the alert will resolve automatically.
- In addition, the machine state becomes critical, because it prevents the service from functioning as expected and the KMS service will not be able to publish itself in DNS. In this case, disable DNS publishing for this service from Console Tasks.

- Periodically check the Alerts view in the Key Management Service folder for low count alerts to ensure that activation is ongoing.
- If the low activation count value is reached, the service will enter into a Warning state.
