I hope this isn't too much of a Windows question for a Linux forum. =) I have Remote Desktop setup on a Windows XP Professional machine (Start->Control Panel->System->Remote tab->Allow Users to Connect Remotes), and I even have the main user accounts added to the access list.

I open up tsclient in Linux (FC5, and also try rdesktop [ip address]), and I am able to get a graphical login prompt from the Windows side. However, when I type in the user name and password (that I already know is added to the access list in Windows), it says "The system could not log you on. Make sure your User name and domain are correct....[they are]." I feel like something is misconfigured on the Windows XP Pro side, but I can't figure out what. Can anyone who has successfully used rdesktop tell me how they get it to work?

Now, I believe that I had this exact problem some time ago. I think all I had to do then was log out on the Windows side, then I could use rdesktop from my Linux computer, even though I couldn't see anything on my Windows PC because I was logged out (and the two computers are right next to each other, I should add). I really don't want to use a VNC server to access my Windows PC.

Again, if anyone who has successfully used rdesktop to connect, if they could please just tell me how they setup their their Windows PC to accept the connection, I'd appriciate it. I've searched all over the internet and I can't find the solution to this particular problem. Thanks in advance!

edit: I just tried to remote desktop into my Windows Pro machine from another Windows machine, and I get the same error. I think I'm specifically looking for some running services or something. I really hope somebody can help. There is an unusually small amount of help for this problem out on the web.

edit2: Also, does anyone know if I am able to remotely control this Windows XP Pro machine while someone is logged into it working?

OMG, I just figured out the problem. The Windows Pro machine is not mine. I didn't set it up. So I finally get tired of this problem, and I went into the Windows Username properties to take out all of the spaces of the main username on the PC. It turns out that there were TWO spaces between words. That's just one more reason to favor single-word usernames. This is absolutely absurd.

Anyway, to anyone who is googling into this page, it works to simply enable remote desktop connections in the Control Panel->System->Remote menu. No damn wonder there wasn't any documentation on this issue. It's that simple, and everybody probably already knew how many blank spaces there were in their usernames.

edit: I'm typing this from an rdesktop sesssion right now. =P Stupid, stupid extra username space.
