Adding normal server with Terminal Services to a Domain

Hello,

I have a server that has Remote Desktop Services (Terminal Services) and is not in a domain nor is a domain server.

What would happen to the TS licenses of this server? would they maintain on this server or would they be transferd automaticlly to the domain server? would I need to reinstall them again?

Hope I've explaind well what I am doing, if not ask :)

Thanks in advance for the response.
