“Domain Controller Enforcement mode” will be activated as of 9 February 2021

With the security update of 11 August 2020, Microsoft has addressed a security vulnerability (CVE-2020-1472). This has not yet been closed automatically, as compatibility problems may occur. How to close the vulnerability beforehand is explained in KB article 455722.

List of different Group Policy Templates (Updated)

Active Directory Group Policy Object (GPO) is one of my core topics. I have a lot to do with it in various projects and as a Microsoft trainer. I have collected some templates and links. This link collection should make your search a little easier. Only templates of the vendors or of the projects are listed here. I have consciously avoided third-party policies.

Changes in the LifeCycle of Microsoft products due to Corona

Changes in the life cycle of Microsoft products due to Corona / COVID-19.

Microsoft is extending the current lifecycle for some products to relieve the burden on IT departments. I took this opportunity to update the LifeCycle Diagrams from the articles “Microsoft Lifecycle Diagrams” and “Other Lifecycle Diagrams” from last year.
This time I translated them directly into English.

Setting up Office 365 – Part 2

This article is part of my migration from my old Office 365 to my new Microsoft 365 Tenant. It is also about setting up Office 365, the other Microsoft 365 topics will follow later. I also have written this article intentionally so that it can also be used for setup outside of a migration scenario. Part 1 was about choosing the right edition, setting up the account and configuring the domains and DNS.

Preparing the mail flow for the Office 365 migration

This article is part of my migration journey from my old Office 365 to my new Microsoft 365 Tenant. This article is about mail traffic during the migration and how to avoid data loss.

In May 2015 I have already written the article “Migration from one Office365 Tenant to another Office365 Tenant“. I will adopt and adapt the relevant parts from the old article here.

Website monitoring with PRTG

This time an article slightly outside the Microsoft world. This time there is an excursion into monitoring and the monitoring of web servers under Linux. Some know this, nothing is worse than when the website you want to visit is not reachable. Since this happened to me 2 times in 2 days, the web server has hung up and I could not find the error, something had to be done.

Update, maintain and use Windows Image Files (WIM)

Since I’m very busy with deployment and rollouts, I thought I’d write a few basic articles that I could refer to. This sometimes saves you some time in workshops for the more interesting things or gives administrators incentives to automate things.

End of the Windows 7 Life-Cycle – Migration approaches from the field

Soon it is time, for Windows 7 the extended support ends on 14.01.2020. As with every end of operating system support the end comes “completely surprising”, okay, not really. At the beginning everything looks so far in the future, it is still x years time. But in the end, the problems appear.

I already saw this at the “surprising” end of XP. But there are also cases where migration is not so easy. Special problem areas can be interfaces to special Hardware. For instance, measuring workstations or production control systems. If a measuring instrument with current Windows 10 support directly costs a few tens of thousands of Euros, then you consider the investment.

Creating Users Easily with PowerShell

As most people know, I like to make my life easy at work. That doesn’t mean I’m afraid of work, I just like to automate or simplify it where I can. I like to use PowerShell for this.

Another reason besides the convenience or lack of time why you should solve tasks through scripts is a consistent level of quality. Let’s face it, who doesn’t know this, even if there are checklists, you might forget one step when you get distracted.

Microsoft Azure AD – the license types and functions

Welcome to part 2 of the Azure-AD series. This part covers license types and features. We will also deal with the topic of license procurement and licensing possibilities. Due to the scope of functions, I cannot describe all functions contained in the individual licenses in this article. But I try to cover as much as possible and to provide links to further information.
