If UAC is enabled and Admin Approval Mode is enabled for the built-in Administrator for example, you might have problems accessing network drives from an elevated command prompt. This behavior is expected, since in Admin Approval Mode all apps run as a standard user by default. If a program is elevated, it runs under a different session than the non-elevated user.

Microsoft suggests following fixes or workarounds:

1. Remap network drives via bat file or manually
2. Create this registry key, which creates a link between both sessions:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System DWORD EnableLinkedConnections 1

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:

In this day and age having an on-premise Active Directory is not mandatory, especially if you are a small and/or new organization. Most of the services will be in Microsoft 365 anyways, so why bother maintaining local AD?

If you have an Azure Active Directory Tenant, users are allowed to join Windows 10 devices to the AAD domain by default.

In the AAD Portal, under Devices > Device Settings, settings can be adjusted to the organization's needs.

Joining the device is very easy. Just open the modern Settings app in Windows 10 > Accounts > Access work or school > + Connect. Then select Join this device to Azure Active Directory.

After logging off, any user that is a member of the tenant can log in with their email address/Azure AD account.

It is not possible to delete or rename a folder that contains a blank space at the end with Windows Explorer. It can only be done by using this cmd command:

rd "\.\C:\temp\my folder "

You probably have stumbled upon this common problem: When logging into a Domain Computer with a Domain user, this error appears: The trust relationship between this workstation and the primary domain failed.

What does it mean? Well, it basically means that the Domain Computer cannot authenticate against Active Directory, because the Computer Account password on the workstation is not valid anymore (this can occur when using Sytem Restore or when restoring from a backup).

How do you solve this issue? Pretty easy. Just remove the computer from the Domain and re-join. That works, but there is a cleaner and faster solution with one line of PowerShell code:

Test-ComputerSecureChannel -Repair -Credential (Get-Credential)

You will need to enter domain user credentials that can create or modify computer accounts in the Active Directory Domain.

You can check if the password of the Domain computer changed by viewing the attribute pwLastSet in the Attribute Editor.
