What is the first step to troubleshoot an endpoint that is not responding?

The first step to troubleshoot an endpoint that is not responding is to check network connectivity and the status of the Tanium Client. This is crucial because many issues arise from basic connectivity problems or the client not functioning correctly. If the network connection is unstable or the client is down, communication between the endpoint and the Tanium Server will be disrupted, preventing the endpoint from responding.

Verifying network connectivity ensures that the endpoint can reach the Tanium Server and other essential services, while checking the status of the Tanium Client confirms whether it is running as expected. This step provides a solid foundation for further troubleshooting, as it addresses the most common and fundamental issues before considering more complex solutions, such as updating or reinstalling the client or restarting the server. By confirming both points, you can effectively narrow down the root cause of the problem in a systematic manner.
