I am using a pre-installed Windows server. Why can’t I connect using RDP?

If you’ve never used the server before, try logging in over VNC, as our pre-installed images require some setup (such as the initial password creation) to be performed before RDP can be activated.

If you can login over VNC but cannot connect over RDP, you may need to disable Microsoft’s ‘Network Level Authentication’ (NLA). This offers an additional layer of security on top of normal RDP authentication, but is not compatible with older clients such as those included in XP or older versions of Windows.

See How to change the RDP authentication settings (Microsoft article).
