I tried connecting to Windows 8 using its built-in Remote Desktop feature, but for some inexplicable reason, it requires that no users are logged in on the target machine before a remote user can log in.
This has never been a problem with
rdesktop on Unixen; I could
rdesktop from as many machines as I wanted and any logged-in users would never notice a thing.
What's the problem with Windows? Any way to allow concurrent local and remote logins to a Windows 8 machine without hacks or cracks? The "guides" on how to do this that show up in the Google results all suggest replacing a system DLL with a hacked one, but that's not acceptable.
