Troubleshooting Connectivity Issues
If you are experiencing connectivity issues while trying to activate your Server 2016 using KMS and are encountering the error message “KMS Connection Failed,” there are a few troubleshooting steps you can take to resolve the issue.
First, ensure that your server has a stable internet connection. Check the network settings on your server to make sure it is properly configured and able to reach the KMS server.
If the issue persists, try restarting the KMS service on your server. Open an elevated command prompt and run the command “net stop sppsvc” followed by “net start sppsvc.”
You can also try to reset the TCP/IP stack on your server. Run the command “netsh int ip reset” in an elevated command prompt and then restart your server.
Checking System Configuration
| System Configuration Check | Details |

Verifying License Status
To verify the license status on your Server 2016, you can check the activation status using the command prompt. Open Command Prompt as an administrator and type slmgr.vbs /dlv to display detailed license information. Look for the “License Status” field to see if the server is activated or not.
If the activation status shows as “Licensed” then the issue may lie with the Key Management Service (KMS) connection. You can troubleshoot this by checking the KMS server settings and ensuring that it is reachable from the server.
Additionally, make sure that the server has internet connectivity to communicate with the KMS server. You can check the network settings and firewall rules to ensure there are no restrictions blocking the connection.
If the issue persists, you may need to contact your system administrator or IT support team for further assistance in resolving the Server 2016 activation error related to KMS connection failure.
Ensuring Network Access Permissions
- Check the firewall settings to ensure that the Key Management Service (KMS) traffic is allowed
- Verify that the server has proper network access permissions
- Ensure that the KMS server is reachable from the client machine
- Confirm that there are no network issues causing the connection failure
- Double-check the DNS settings to make sure that the KMS server can be resolved correctly
