A user cannot access a file server after a period of working on it. What should the administrator do first to troubleshoot?

When troubleshooting an access issue to a file server, it is essential to gather as much relevant information as possible about the problem. Asking the user what they were doing prior to losing access provides insight into the circumstances surrounding the issue. This inquiry can reveal whether there was a particular action or event that may have led to the failure, such as changes in network settings, user permissions, or software updates.

By understanding the user's actions, the administrator can more effectively narrow down potential causes of the problem. This initial step can guide subsequent troubleshooting steps, such as checking for network connectivity, verifying user permissions, or investigating server status, making it a crucial first move in resolving the issue effectively.
