Navigate to Computer Configuration > Administration Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client.

If you're seeing PORT ERROR on Windows, it's likely that the driver did not get installed correctly for some reason. To fix this, navigate to
C:\ProgramData\ZeroTier\One\tap-windows\x64
then right click on the file zttap300.inf and select Install from the menu.
Note: The folder C:\ProgramData is hidden by default and requires Administrator privileges to access.
If you have other VPN or similar apps that require network drivers, you may want to try uninstalling them, probably rebooting, and reinstalling ZeroTier.
Windows may show the ZeroTier virtual network port as a 100Mbps or 10Mbps port. This is incorrect. It's a software defined port with no intrinsic speed limit. Windows doesn't show accurate numbers for non-physical ports that have no actual interface device.
If you're having trouble using ZeroTier on Windows, the following steps may be of assistance.
Make sure you have Administrative Rights on your user.
Uninstall any other VPN software that could be conflicting with the ZeroTier setup.
Check for any antivirus software that has additional "Internet Security" features, that could be blocking installation and trying to assume Windows Firewall functionality.
Try different combinations of rebooting and reinstalling ZeroTier.
Side note: there were reported VPN issues in certain versions of Windows 10; those have their own fix via Microsoft.

If you continue to have issues, please check github for any existing issues, or report a new one. Thanks!
