Hello Al Wayne,
What is your current situation?
Please share us more information for better analyzation as Frederik Long mentioned.
Do you mean that the Dell XPS 8700 and laptop can’t RDP to work Windows 7 machines, but the Windows XP laptop can RDP to?
Please take the following steps for troubleshooting:
1. Share us the result of command ipconfig /all in the source and destination computers
2. Check if we can ping the Windows 7 machines from the Dell XPS 8700 and laptop
Best regards,
