Testing enabled SSL and TLS protocols on servers is something I have to do for hardening and security purposes. Of course, you can do that using PowerShell with the Test-TlsProtocols Module from TechnologyAnimal 🙂 In this blog post, I will show you how.

Using the Indented.Net.IP PowerShell module for IPv4 Subnet math
I still do some networking, although not as much as I did during my CCNP certification, and I eventually memorized subnet calculations. That, and using IP Calculators 😉 In this blog post, I will show you how you can use Chris Dent's PowerShell module for that.
Using Get-NetNeighbor to retrieve MAC, Vendor and IP details in PowerShell
I just moved to my new house and reconfigured all my network equipment. I wanted to know which MAC address belongs to which Vendor and the corresponding IP details, as well as the open ports. In this blog post, I will demonstrate how to use Get-NetNeighbor and NMAP for this purpose.
Using the Get-NetView PowerShell Module for Network Troubleshooting
Collecting enough logs and information from a system with networking issues can be difficult. You always need just one more to troubleshoot the problem. 😉 In this blog post, I will show you how the built-in Get-NetView module can help you collect all the necessary logs and information.
Retrieve blocked DNS queries from PiHole using PowerShell
I use PiHole for Ad-blocking at home, and yes, sometimes that causes some issues if it blocks Microsoft (Or other) management addresses. In this blog post, I will show how you can live-track blocked DNS queries and get some insights while troubleshooting 🙂
Fixing Windows 11 24H2 – No Internet Access Issue using PowerShell and Intune Remediation
There are articles and forum posts from people who upgraded to Windows 11 24H2 and are experiencing Wi-Fi issues. In this blog post, I will share an Intune Remediation script that may resolve the issue on your devices.
Use PowerShell to create report of a DTS Compliant NPS log
One of our customers had issues authenticating clients using NPS. One of the first things you do is... I read the NPS logs, and they were DTS Compliant formatted, a bit of a pain to read and search 🙁 So, I used PowerShell to create a nice log for me in either a GridView or an Excel file. In this blog post, I will show you how!
Changing DNS settings on Windows devices
During migration projects, I regularly change the DNS server settings of statically configured adapters on servers. (For clients, you can change the DHCP settings, and they will receive the new settings when the lease expires) For servers, it can be a lot of work doing it manually. In this blog post, I will show you how to automate that 🙂
Reconfigure Hyper-V External switch to the correct Network Adapter
If you use Hyper-V on your laptop, you will probably recognize this... You work at home, go to the Office and use Wi-Fi instead of the wired connection at home. You boot your VM, and... No network?! *sigh* You must change the External Switch again in your Hyper-V configuration. In this blog post, I will show you how to change it automatically using PowerShell.
Test if Microsoft services TCP ports are accessible
In a previous blog post, I showed how to retrieve all the Microsoft Services FQDNs, ports, and IP addresses. It's nice to know those in secure environments where not everything can go onto the internet, but how can you test if they are accessible? This blog post will show how to test most of these services using PowerShell.
