If you receive any of these messages:

  RDP Disconnected! Error Code: 2056

  Any License error regarding Windows Terminal Server

You can always try to delete the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing

You can delete the complete key or just the content of the subkey “Store”.

Afterwards you'll have to start the rdp client as an administrator to recreate these keys.
