ConfigMgr

Set primary and secondary DNS server addresses using ConfigMgr and PowerShell

by

Introduction

Just a very quick nugget, finishing up this year of IT.

We needed to change the configured DNS server addresses, on a good bunch of (non-domain joined) servers before heading into 2022. Per usual, I don’t like to do stuff manually, so I took the opportunity to write up a PowerShell script in order to assist us.

I figured this is something anybody might find useful, so I wanted to share the script I ended up creating.

For your convenience, I’m also illustrating how this can be used in combination with ConfigMgr, as this obviously was a requirement for automation purposes.

Happy New Year! 🙂

Windows 10 Toast Notification Script Update: Custom notification app and more built-in prevention from disabling toast notifications

by

Introduction

It’s been a while since the last update on this script. I admit that. Better late than never, I guess.

This update brings a slight improvement to the looks of the toast notifications, and (almost) definitely removes the option for the end-user to disable the notifications as well.

Also, I was wondering about naming the script differently. The script surely works with Windows 11 too, but seeing the entire toast framework was introduced with Windows 10, and Windows 11 behind the scenes is still appearing as version 10.0, I will stick with the current name.

Getting started with Remote help with Intune and Microsoft Endpoint Manager

by

Introduction

Remote help is the brand new and sought-after feature, which provides classic remote assistance capabilities (almost) natively to Windows. Remote help was announced during this years Microsoft Ignite, and started its public preview rollout last week.

Remote help is integrated with Microsoft Endpoint Manager, and this blog post serves as my first look into getting started and using this delicious new feature.

TL:DR: Find a short video recording of the Remote help workflow down in the post. 🙂

Enable ‘Block abuse of exploited vulnerable signed drivers’ in a jiffy using PowerShell and ConfigMgr

by

Introduction

I find this highly relevant to share at this day. Especially in regards to yesterday’s ‘false positive’ situation, where a lot of system admins got a good scare, when Defender for Endpoint reported that “Suspicious ‘PowEmotet’ behavior was blocked’ on a high percentage of the enrolled devices.

What I really mean by this, is that when you have the option to reduce the attack surface of your environment, you should look into doing so ASAP.

Let’s say yesterdays situation was real, and you for whatever reason didn’t have behavior monitoring enabled in Microsoft Defender Antivirus. You would regret that pretty soon after being hit, when you realize that it could have been prevented.

Same goes for above. Rather look into enabling this new ASR (Attack Surface Reduction) rule today, rather than later after being compromised.

Back to basics: Modifying registry for the CURRENT user coming from SYSTEM context

by

Introduction

Back in the days, when I started out being a newbie in the software deployment world, I had no real grasp about the different contexts (USER vs. SYSTEM), and I found it to be a trivial task to combine the two.

Today I find it an obvious approach, and in this post, I will give a quick example of how to modify registry for the CURRENTLY logged on user, while delivering an installation in SYSTEM context.

Oftentimes the scenario is, that you need to deploy software which requires local SYSTEM permissions, and while doing so, you’d like to modify the registry for the CURRENTLY logged on user.

Install Lenovo Drivers and BIOS directly from Lenovo’s Driver Catalog during OSD using Configuration Manager

by

Introduction

This is something that I’ve wanted to do for a while; to always install the latest BIOS and drivers automatically during OSD.

Keeping BIOS and driver versions up to date, can be a tedious and time consuming task, and I wanted to take on a more cloud-like approach.

For that reason, I’ve spent some time on Lenovo Thin Installer as well as Lenovo System Update, but they didn’t quite live up to my expectations and need for flexibility.

Instead – and by coincident – I stumbled upon this awesome PowerShell module: jantari/LSUClient

It does exactly what Thin Installer and System Update offers, as well as giving you the flexibility of PowerShell. What’s not to like?

Install the new Remote Desktop Connection Manager (RDCMan) with ConfigMgr and PowerShell

by

Introduction

Another kickstarting blog post, getting into the swing of things again after a somewhat lacking period.

Now, RDCman has been revived and arrived last week in a new version 2.8.

For fun and giggles, I did a short PowerShell script which uninstalls the old version (2.7, registered with windows installer) and downloads the new version 2.8 directly from live.sysinternals.com.

This is a little something on the script itself and how to put that to use with ConfigMgr.

Connect to your Configuration Manager environment with PowerShell ISE addons

by

Introduction

A quick post, serving as a kickstarter for my blogging activities, here (almost) post the covid-19 situation.

Today’s topic is probably not something new for a lot of the amazing IT-pros, who’s already familiar with PowerShell ISE and the Configuration Manager PowerShell module.

Nonetheless, I figured this would be a great way to kickstart my blogging activities, while someone else hopefully will learn something new along the way.

Windows 10 Toast Notification Script Update: Improved re-run behavior with ConfigMgr and allow running in SYSTEM context

by

Introduction

A new version of the Windows 10 Toast Notification Script is here. The script is now being on version 2.2.0.

This version brings the option to run the script and thus display toast notifications coming from SYSTEM context.

A requirement has been so far, that the script is being run with the logged on user’s credentials. This is still recommended, but for scenarios where this is not possible, like running this with a task sequence (task sequences always run as local system), this new ability will give you the option to display toast notification for the logged on user, even if coming from local system context.

The work done here, with running the script under SYSTEM, is entirely done by Andrew. Thank you!

Also, with a built-in prevention of having multiple toast notifications being displayed in a row, the script is now also better at handling the re-run behavior in ConfigMgr. Having multiple toast notification displayed in a row, is something that can happen, if a device misses a deployment schedule. The nature of ConfigMgr is to catch up on the missed schedule, and this can lead to multiple toast notifications being displayed.

Move away from Group Policy and set wallpaper and lock screen images with local source files and Microsoft Endpoint Manager Intune

by

Introduction

This is something I currently just have done myself, in our own environment, and while it’s neither super technical nor advanced, then I figured it deserved some attention regardless.

I assume most hybrid (co-managed) environments still look towards Group Policy when doing this, because it’s easy and what we’ve always been doing. I’m regularly asked to change our desktop wallpaper and lock screen images, and when things needs to be done in a hurry, you usually stick to the easy solution.

This time though, I was stubborn and insisted on moving away from Group Policy and do it with Intune. The process made up this short blog post. 🙂
