When you connect to a computer (either a Windows client or Windows Server) through the Remote Desktop client, the Remote Desktop feature on your computer "hears" the connection request through a defined listening port (3389 by default). You can change that listening port on Windows computers by modifying the registry.
- Start the registry editor. (Type regedit in the Search box.)
- Navigate to the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
- Find PortNumber
- Click Edit > Modify, and then click Decimal.
- Type the new port number, and then click OK.
- Close the registry editor, and restart your computer.
The next time you connect to this computer by using the Remote Desktop connection, you must type the new port. If you're using a firewall, make sure to configure your firewall to permit connections to the new port number.
You can check the current port by running the following PowerShell command:
Get-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp' -name "PortNumber"
For example:
PortNumber : 3389
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations
PSChildName : RDP-Tcp
PSDrive : HKLM
PSProvider : Microsoft.PowerShell.Core\Registry
You can also change the RDP port by running the following PowerShell command. In this command, we'll specify the new RDP port as 3390.
To add a new RDP Port to the registry:
$portvalue = 3390
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp' -name "PortNumber" -Value $portvalue
New-NetFirewallRule -DisplayName 'RDPPORTLatest-TCP-In' -Profile 'Public' -Direction Inbound -Action Allow -Protocol TCP -LocalPort $portvalue
New-NetFirewallRule -DisplayName 'RDPPORTLatest-UDP-In' -Profile 'Public' -Direction Inbound -Action Allow -Protocol UDP -LocalPort $portvalue
