I have a remote computer that is running XP Pro - it is a newly installed computer that is on a network with 20 other XP pro computers. I can log on to the Server (running Server 2003) via Remote Destop and then I can VNC Viewer to any client computer. When I VNC to the specific computer (I will call it NEWCPU) i have no problem. I can also VNC or Remote Destop from the server to any other PC. If i log off of NEWCPU and then try to logon via either Remote Destop of VNC Viewer it will not accept any password, thus refusing my attempt to log on. The next day I can log on to NEWCPU one time only again. Any ideas as to what may be the problem?
