Remote Desktop Assistance not working on LAN connected computers.

I'm trying to remotely control some computers on the router in my home.  I have a switch connected to the router also, but all the computers are part of the same network. Here's a screenshot of the message I get when I try to connect:
remote-desktop.jpgDo I have to enable port forwarding on my router to make this work?  Since all the machines are on my LAN I wouldn't think so.  I could try ultraVNC or another app like it, but I'm afraid that will fail too.   All the computers are running Windows 7 64 bit, either premium or pro.

    Yes, you will need to forward the port. Your router is, I assume a firewall.

    You may want to give team viewer a try. Its free for personal use.

    - check you are able to ping with computer.
    - Check RDP is allowed in Windows Firewall.
    - Check Remote Desktop is enabled not Remote Assistance, both are different.RDP- Check RDP port is not redirecting to any other port. Check this registry value

    it should be 3389, if something is different then you will need to use that dell7two:3390

    It should be be issue with your Network firewall, but it can be issue with windows firewall.

    Remote Utilities works.  It's not as easy to use as TeamViewer, which I do use in some situations, just not this one.
    Thank you for your suggestions.

    And neither TeamViewer nor Remote Utilities requires port forwarding.
