For many Admins like myself that work in Notepad all the time, I am happy to say that the team have done what we have all been wanting for a long time and that is firstly have the application mirror what theme or settings you have in the OS and allow multiple tabs instead of having multiple sessions of Notepad open. As you can see in the image below, you have the ability now to add all the tabs you want (maybe not too many :-)) and I prefer dark mode, so this is a welcome change. If you want to read more about this, head over to the Windows Insider blog (link below) and if you are registered ..read more

In our environments, there may come a time when you need to make changes, for example you may need to retire servers as your footprint is reducing or you have a problematic server that you want to remove, which-ever scenario you are in that involves, it may require uninstalling or hard removing a server. Below is a scenario where two “healthy” servers had to be removed but resulted in having to do some removal in the registry to fix it. Problem: In this scenario we were running Windows Server 2019 Core Edition and the uninstall has to take place using the command line as you have not graphical ..read more

For those familiar with Exchange and have been working over the years with it, whether it is Exchange 2013, Exchange 2016 and Exchange 2019, you normally login to the Exchange Admin Center (EAC) and then create your certificate request directly from there. With Exchange now, you have to use PowerShell to create your certificate request as the option has been removed as shown below: We need to use the Exchange Management Shell (EMS) to firstly generate our certificate request and then export it to a file after that so we can upload the information to a certificate authority like Digicert etc ..read more

With Windows Server 2022 now supported, I moved my lab from Exchange 2019 running on Windows Server 2019 Core to Windows Server 2022 Core. I did a complete reinstall as you cannot do in-place upgrades on Exchange Servers and domain controllers. My DC’s are also now running Windows Server 2022 Core.

The Windows 11 landscape keeps updating and what used to be “Windows Terminal” if you right-clicked the start menu, is now called “Terminal” as shown below: The cool part is that you can have all your command line tools open in one application. For example, I have Windows PowerShell, Command Prompt and Azure Command line open in multiple tabs: One thing to take note of here is that if you click the + button next to a tab, it will open a new Windows PowerShell window because it is set as the default and we will cover the settings in just a minute.

ESET Security product for Exchange does a pretty good job in handling emails and blocking malicious content but I have found that some versions have caused headaches for Exchange and I have had to roll back to a previous version. You have the ability to perform two options with upgrading. Either you can do an export of the config and then uninstall the current version or you can do an in-place upgrade. I went with the in-place upgrade option and it went through without an issue. Here are some screenshots of the upgrade and the different steps: Post upgrade checking. After the servers in the E ..read more
