One or a few users are not able to connect to their mailbox using the newest Outlook version there is? Well the issue might be TLS 1.2 not being active on the user’s side.

Just set this registry key and you should be good to go:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings

or

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

DWORD SecureProtocols 00000A80

HEX A80 or decimal 2688 enables TLS 1.0, 1.1 and 1.2, while decimal 640 only enables TLS 1.0 and 1.1.

Having odd issues with the task bar/random task bar freezing on Windows Server 2022 RDS? Or explorer.exe using around 10% of the CPU for every user that is logged in? This might save your day. This issue occurs if you have MS Teams installed on the RDS.

First of all, export the registry path HKLM\SYSTEM\Software\Microsoft\TIP\TestResults\27641370 and look at the file size. If it is around 40MB in size, then you have the same issue.

To resolve the issue, delete the key and disable the TabletInputService service (Touch Keyboard and Handwriting Panel Service). Afterwards, take ownership of C:\Program Files (x86)\Common Files\Microsoft Shared\ink\TabTip32.exe and C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe and rename both executables into TabTip32.exe.orig/TabTip.exe.orig.

After that, reboot your server.

Windows Server 2022 is new and has to be the best Windows Server there is right? Not at all. Microsoft has added a recovery partition (like in Windows Client versions) that prohibits you from expanding the boot disk like you usually would in older Windows Server versions.

Anyway, here are a few diskpart commands that will help you delete the recovery partition and allow you to expand the boot disk:

diskpart

list disk

select disk 0

Make sure partition 4 is the 523MB Recovery partition

select partition 4

delete partition override

Just recently I learned that Microsoft ClickOnce Applications are a pain in the ass and cannot be published as Published Applications the usual way through Citrix Virtual Apps and Desktops.

Usually the message below shows up before starting or installing the application (which is on a user basis – I absolutely hate that. Thanks for that Microsoft and Developers). If you try to publish the file ending with .application nothing will happen.

Creating a BAT file and publishing that bat file will show the prompt and the desired application will start:

cd /d “C:\Windows\Microsoft.NET\Framework\v4.0.30319”

start dfsvc.exe

start “C:\Program Files (x86)\Internet Explorer\iexplore.exe” “http://webserver/app”

This does also work:

start “C:\Program Files (x86)\Internet Explorer\iexplore.exe” “\\fileserver\share$\bestsoftware.application”

Have you been having issues with Microsoft Azure AD Sync service after a simple reboot of the Windows Server? These simple steps might help:

Copy model.mdf and modellog.ldf files from

C:\Program Files\Microsoft SQL Server\150\LocalDB\Binn\Templates

to either

C:\Users\ADSyncxxxxx$\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\ADSync2019

or

C:\Windows\ServiceProfiles\ADSync\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\ADSync2019

This issue should not occur starting from version 2.1.1.0 of MS Azure AD Connect. Read the Microsoft doc below to perform a manual in-place upgrade of Azure AD Connect.
