Win 7 Pro not connecting to remote Win 7 pro via port 3389 RRS feed

  • Question

  • I have a new Dell XPS 8700 Win Pro 64 bit that will not connect to work machine of same specs, i.e, XPS 8700 Win 7 Pro. Ironically an old lap top running XP Pro will connect to work computer. I have a new Dell laptop with Win 8.1 pro that will not connect either.  I tried everything, uninstalled Symantec End point, shut off the Windows Firewall, did a complete hardware check via Dell Diagnostics, made sure network discovery was on as well as all remote services, turned on RD, changed every setting on the  RD dialog box, pinged the external IP and it timed out. None of the forums seem to have an answer and I am at wits end. I set up 15 machines at work under Win 7 for RD and all are working with Win 7 Pro.

  • You need to post more details, in particular:

    • What is your exact networking setup?
    • Are there any routers involved? If yes, did you create the necessary tunnels?
    • Do you use a VPN?
    • Did you test your port connectivitiy with telnet.exe?
    • Did you turn off the host's firewall during testing?
    • Did you check the host's registry to ensure that it listens on port 3389?

  • 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,
