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.

In Microsoft 365 / Exchange Online, to connect a soft deleted mailbox, you have need to use the cmdlet New-MailboxRestoreRequest to restore the mailbox to another user.

Get-Mailbox -SoftDeletedMailbox | select guid

Get-Mailbox <NewMailbox> | select guid

New-MailboxRestoreRequest -SourceMailbox <GUID> -TargetMailbox <GUID of new mailbox> -AllowLegacyDNMismatch

To check the status of the restore:

Get-MailboxRestoreRequest | Get-MailboxRestoreStatistics

If you are noticing seemingly random RDS session freezing on Windows 10/11 clients, this registry key might help. It disables the UDP protocol for RDP connections, which Microsoft enabled by default since Windows 10 1809/1909. I have had this issue occur on Windows 10 21H2.

HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services\Client

DWORD fClientDisableUDP 1

A reboot of the machine was not needed, after closing the RDP session and reconnecting, TCP was being used. You can check which protocol is being used by clicking the symbol at the top:
