virtualbox.org

Hello,

since I'm on Windows 10, it became impossible for me (and many friends) to connect to RDP servers I have created with VirtualBox.
When I try to connect to a server with mstsc.exe on Windows 10, I have an error (see the screenshot)

but when I try to connect to a server with Windows XP, it works

Is it a bug? I'm not the only one with this problem, so I do not understand...

Regards

I have encountered the same problem. In English it basically says it cannot connect to the remote connect to the remote computer over RDP. And to try it again.
When I use the 'normal' RDP port 3389 there is no problem. Only for those VMs that I have configured using a different port (because 3389 is already occupied.)
It looks like a Windows10 firewall issue.
Meanwhile: Have you found a solution?
