I want to access from a Win2000 system with a MS Remote Desktop Client through the Internet
another WinXP Prof computer with a Remote Desktop Server.

Sorry for this newbie questions about this scenario:

Is an access over the internet possible or is a connection MS RDClient->RDServer only possible inside a LAN?

As far as I heard the normal way is to create a key on the server system and pass it to
the client. So it is not possible to login from the Remote Desktop Client without the key file
even when I know the server IP, a login name and passwort on the server system?

Is there a difference between the Remote Desktop Software and the so called "Terminal services" or is the same ?

Can I access with the newest MS Remote Desktop client older MS RD server versions (read: Is there an downwards compatibility)?

How do I find out if the communication requires RDP1 or the newer RDP2?

Thank you for answers
