There is a particular option in the Remote Desktop settings on the host
computer that might need to be fixed. Open [ Control Panel > System > Remote
settings ] and look for the Remote Desktop box. Make sure that, on the host
computer, the radio button is filled next to "Allow connections from
computers running any version of Remote Desktop (less secure)". I think XP
uses a different version of RDC software than Vista, which might be the
problem. If that's not it, then I don't know what else to suggest. Good
luck!
