I have been experimenting with using PsExec of the Sysinternals suite to gather information from remote Windows systems for diagnostic use. I’ve found it to be a powerful tool, especially when integrated with PowerShell scripts. It is able to execute a script or command on a remote machine and return the output back to the…

PowerShell – Programmatically Determine the Primary User of a Device
Configuration Manager includes the device property and concept of UserDeviceAffinity, with which the Primary User of a device can easily be determined and referenced. But, what if your environment does not have MECM in place? MECM is a lot of overhead for a small environment. How might one maintain this capability? Well, user log on…
PowerShell- Launch Applications With Other User Context Within Interactive Session
There are many reasons one might want to establish a workflow in which they can quickly launch PowerShell or the ISE with alternative credentials from their interactive session, such as executing a script with a more privileged user context. To do so, create a script like the one below: Then, create a shortcut to execute…
Azure – Malicious Authentication Emulation and Mitigation
The attack surface of a cloud tenant should get a lot of consideration. It is important to understand that some legacy protocols, like SMTP, are not capable of accommodating multifactor authentication; and, although they are largely being deprecated, we may still see them in use. Attackers are particularly fond of these legacy protocols, as they…
PowerShell – Indulging the Memosphere – Invoke-Tune Function
I let my curiosity get the better of me, and I put together a PowerShell function for the purpose of creating music using PowerShell’s built-in console beep feature. And, in the very essence of internet meme culture, I present to you my triumph—a PowerShell function that unleashes the timeless anthem of Rick Astley’s ‘Never Gonna…

For the gentleman requesting assistance with my UltimateOCD script, I have revised it further to allow you to easily provide some parameters like the target directory, directory exclusions, and a custom temporary directory path. In addition, I have revised the logic to use the “product” & “x.x.x” (version number) directories to detect Oracle client instances….

This is for the gentleman that kindly requested a modification of my UltimateOCD script to allow for batch deployment. Please note that this preliminary example is untested. I will be testing and revising in the days to come, but this may get you on the right track with some testing of your own. In the…
PowerShell – Update to Ultimate Oracle Deinstaller
A few months back, I had built what I dubbed the “Ultimate Oracle Client Deinstaller.” It could handle the deinstallation of Oracle database clients 11g, 12c, and 19c to include having multiple clients installed- even if they share the same Oracle_Home location. Recently, I ran into some alternate configurations of the Oracle client that required…
PowerShell – Add + Trust PsGallery & NuGet
If you do a lot of PowerShell work, you may find yourself frequently using NuGet or PsGallery. I’ve put a couple functions together that quickly add the PsGallery repository and NuGet respectively, and add trust to these sources. These functions were built to be modular so they could be modified for other sources as well….
PowerShell – Add Hosts to AD Group
Here’s another simple script I put together. It allows you to specify a Security Group in Active Directory, and add a list of hosts to this group. Simple, but yet another tool that every SysAdmin should have in their repository.
