network-diagnostics

Test network connectivity on Windows by running PowerShell cmdlets like Test-Connection and Test-NetConnection. These commands verify host reachability and check if specific ports are open, providing clear output suitable for scripted automation.

Troubleshoot DNS resolution in PowerShell using the Resolve-DnsName cmdlet. It performs DNS lookups to diagnose name resolution failures, helping you identify whether connectivity issues stem from DNS mapping errors or network unavailability.

Inspect active TCP connections and network interfaces using the Get-NetTCPConnection PowerShell cmdlet. This allows you to view current port usage and interface states directly from the Windows command line for troubleshooting.

Trace a network route in Windows using PowerShell to diagnose connectivity paths. By executing trace route commands, you can identify where network packets drop or experience high latency between your machine and a target host.

Standard network diagnostics in PowerShell use built-in cmdlets such as Test-Connection and Resolve-DnsName. Basic connectivity and DNS checks typically do not require elevated privileges, making them accessible for standard scripted automation.

Network diagnostic scripts fail if required PowerShell cmdlets are missing or network interfaces are down. Ensure your environment supports Test-NetConnection and Get-NetTCPConnection, and verify the target host is reachable to get clear output.
