Remote Desktop Connection to Server….

When I try to remote desktop into 2003 server from an xp machine, I get an error “Remote Session was disconnected because there are no Terminal Server client access licenses available for this computer….

I can log on to other XP computers and servers remotely no problem immediately after being “rejected” by this one server.

Now, I can go to different XP machine and attempt to remote log on to the same server that “rejected” me before and using the same creditionals, I can get in no problem.

It appears that it is something on the first XP machine but I can’t find anything as to why. Looking for help/ideas?
