User Unable to Access Network Resources

D.

The FIRST thing that a network technician should do when a user reports being unable to access network resources after making some changes in the office is to ask what changes were made.

This is because understanding the nature of the changes made will help the technician narrow down the possible causes of the issue. It will also help the technician determine if the changes made were related to the network configuration or if they were related to something else, such as an application or a local computer setting.

Once the technician has a clear understanding of the changes made, they can proceed with the appropriate troubleshooting steps. For example, if the changes made were related to network configuration, the technician might want to check the user's IP address to ensure that it is correctly configured for the network. Alternatively, the technician might want to do a ping test against the servers to see if there are any connectivity issues.

However, it's important to note that without first understanding the nature of the changes made, these troubleshooting steps may not be effective or relevant to the issue at hand. Therefore, asking what changes were made should always be the first step in troubleshooting network connectivity issues.
