Which utility is used to troubleshoot network connectivity issues in Windows?

The use of Windows Network Diagnostics as a utility for troubleshooting network connectivity issues is highly relevant because it is specifically designed to help users identify and resolve problems related to network connections. This tool can automatically detect network configuration issues, check connections, and analyze problems like DNS failures, network adapter issues, or problems with the network path itself. It provides a guided approach to troubleshooting, often suggesting possible solutions based on the detected issues.

In contrast, Device Manager is primarily used for managing hardware devices and drivers, Event Viewer is focused on logging and analyzing system events and errors, and Task Manager is intended for monitoring system performance and managing running applications and processes. While these utilities can provide valuable information or support in certain contexts, they do not directly target network connectivity problems in the same way that Windows Network Diagnostics does, making the latter the most suitable choice for addressing such issues.
