I want to Create a remote only user for Remote Desktop.

I have 2 Win Xp Pro's, one with Remote Desktop enabled.
On the computer with the Remote Desk. Enabled, I want to create a user that can only logon remotly.

I created a user in the group "Remote Desktop Users" only on the Remote Desk. Enabled computer.
When I use Remote Desktop to login from the non-enabled Remote Desk. PC with the user, It logs me on and then logs off before I even get to see the desktop.

The only way I'm able to stay loged in, is if I add the user to the "Users" group.
The problem with that is, the user can logon localy.

Anyone know how I can Create a remote only user for Remote Desktop?
