Terminal services

I open my XP SP3's group policy and cannot find the Terminal Services tree node ?

Where is it ?

Could someone help me please ? Thank you

Make sure you're opening the full group policy, and not just the local policy:

Then, navigate to:
\Computer Configuration\Administrative Templates\Windows Components\Terminal Services
or
\User Configuration\Administrative Templates\Windows Components\Terminal Services

Thanks Craig, I am trying to remote-connect my computer to another XP client on the same network.
I referenced http://sig9.com/node/110 and read their comments but still am unable to find a solution to do it right. Everytime I try to log on to that computer that is in use, he will be logged off automatically. If he logs on again, I'd be kicked out.
What I did followed exactly as that link stated, then I also set the connection limit number to 3 or more, I also enable rules for connections by allowing them to be without permission.
What should I do or re-do next to get it connected remotely without problems ?

Thanks.

That's because Windows XP is not a SERVER OS. This means that only ONE concurrent login is allowed at a time. Same with Windows Vista and Windows 7.

The only OS allowing multiple concurrent users would be a SERVER.
