Okay so we have SBS 2011. I've had the users set up to use remote desktop, and has been working fine for the past couple years. Today for some reason, in particular only XP SP3 machines, the users get a message saying, "You do not have access to logon to this session."
I used a user account to login to a windows 7 machine, and it works just fine. Also I can use my domain admin account to login to this xp machine just fine.
What would cause this???? Any help for a fix?
