Situation: The client has been running Remote Desktop Services for users to run an auto-start application remotely. It works on Windows 2008 R2 and 2012 R2 Server. However, it doesn’t work on Windows 2016 and 2019 server. This is Starting program settings in User’s Environment.

Cause: This is because of the changes to RCM on Windows 20126 and 2019. Quoted from Microsoft article: Changes to Remote Connection Manager in Windows Server 2016

Changes to RCM

In Windows Server 2012 R2 and earlier versions, when a user logs on to a terminal server, the RCM contacts the domain controller (DC) to query the configurations that are specific to Remote Desktop on the user object in Active Directory Domain Services (AD DS). This information is displayed in the Remote Desktop Services Profile tab of the users object properties in the Active Directory Users and Computers MMC snap-in.

Starting in Windows Server 2016, RCM no longer queries the user object in AD DS. If you require RCM to query AD DS because you are using the Remote Desktop Services attributes, you must manually enable RCM. For more information about this by-design behavior in Windows Server 2016, see RCM behavior in Windows Server.

Additionally, consider the following scenario:

• You install Windows Server 2016 with the Remote Desktop Session Host role.
• You configure a local user account to start an application during logon. You do so by using the Local Users and Groups tool in Computer Management.

In this scenario, you expect the user to be presented with the application in the Remote Desktop Session only. However, by default in Remote Desktop Session Host (RDSH) in Windows Server, a full Remote Desktop Session is presented, and the application setup process in the profile doesn’t start.

Resolution: Also quoted from the same article:

To revert to the earlier (pre-Windows Server 2016) behavior, here’s what to do:

If the server has the RD Session Host Role installed, apply the following registry keys to enable the RCM legacy model. It triggers an Active Directory query to check for RDP profile settings:

• Path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\<Winstation name>\
• Name: fQueryUserConfigFromDC
• Type: Reg_DWORD
• Value: 1 (Decimal)

Then, restart the Remote Desktop Service. If the server doesn’t have the Remote Desktop Service role installed, you must set up an extra registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server

Situation: when you attempt to change the time zone on Windows 2019 Server, you may receive this message: Unable to continue. You do not have permissions to perform this task.

Resolution 1: Login local administrator account and make the change.

Resolution 2: run timedate.cpl Powershell command and make the change.

Situation: The client run robocopy command to copy a directory with spaces, it doesn’t work, for example

robocopy D:\SharedDocs\Air Export G:\Air Export /MIR /COPYALL /XO /R:1 /W:1 /log:c:\aes.txt

Resolution use the double-quotes, for example

robocopy “D:\dy\SharedDocs\Air Export” “G:\Air Export” /MIR /COPYALL /XO /R:1 /W:1 /log:c:\aes.txt

Situation: After a Windows update, you have a problem to printer to a network printer. When you check the Printer Ports, it is empty, and no printer ports listed.

Resolution 1: Disable Print Spooler RPC encryption on both printer server and client

Some Windows update may add more security features and enable the RpcAuthnLevelPrivacyEnabled Registry which key is set to and Windows automatically encrypts RPC communication with network printers on the Windows OS. If shared printer server and client are in different level of Windows Edition, group such as domain, workgroup or home, the client may not be able to add the shared printer even you can see it. Disable the RpcAuthnLevelPrivacyEnabled (which set key to 0) may get rid of error code 0x0000011b. Here is how.

1. Run the Registry Editor by typing regedit on search bar.
2. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print.
3. Right-click on the Print key and select New→  DWORD-32 bit Value.
4. Enter the new key RpcAuthnLevelPrivacyEnabled.
5. Double-click on the new key and set its value to 0 (zero).
6. Restart your computer, and check if it connects to your printer.

Note: you need to do that on both printer server and client.

2. Resolution 2: Manually Add the Printer

1. Go to Windows icon>Settings.
2. Click on Bluetooth and Devices.
3. click on Printers and Scanners.
4. Then click on the Add device button to add a printer or scanner.
5. Follow the wizard to add the printer.
