RDP: No client access licenses

[ATC]

When connecting to a Windows Terminal server using RDP, a client was refused access with a message stating 'there are noe client access licenses available for Terminal Server for this computer'.

Access from other clients works ok, and access to other terminal servers also works ok.

[ATC]

On the client computer, close any active RDP sessions.

Backup and delete any sub-keys under the following registry key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing\Store]

You should now be able to connect normally.
