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:
1. Ping devices locally or remotely
- 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)
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.
