10 PowerShell cmdlets to simplify your network troubleshooting (free PDF)

PowerShell cmdlets offer an efficient way to identify network issues and resolve connectivity problems. This ebook looks at 10 of these troubleshooting time-savers.

From the ebook:

As Microsoft releases newer versions of its Windows client and server OSes, it continues to double down on PowerShell (PS), the framework developed for managing systems and automation. With its ever-expanding list of commands, called cmdlets, PS is poised to aid in configuring just about any settings found within Windows.

While PS boasts a vast number of cmdlets, thankfully most are grouped based on functionality or the service they manage. For the purposes of this article, the cmdlets that pertain to managing network-based settings are all found within the base PowerShell framework.

Before diving into the cmdlets, you’ll need to meet a few requirements to ensure that all cmdlets are available and fully supported:

  • PC with Windows Vista installed (or newer)
  • Windows Management Framework 3.0 (or newer)
  • Switched network (required for most cmdlets to function properly)
  • Broadband internet access (optional, but recommended)

1. Ping devices locally or remotely
Test-NetConnection -ComputerName “Hostname or IP”
The Test-NetConnection cmdlet offers a number of ways to test network connectivity on the LAN and WAN. Enter the command as typed above and the computer will essentially perform a ping to determine if network connectivity between the local device and the target computer or domain exists.

2. Check connectivity based on port or service
Test-NetConnection “Hostname” -Port #
Another feature of the Test-NetConnection cmdlet is the ability to test the connectivity between the local device and the target host by specifying a port number. This is extremely useful for testing services between devices and the ports they communicate on specifically.
