Windows 7 remote desktop help?!

[Dreamflyer]

Hey guys,

I've been trying to setup remote desktop on my laptops...
I don't have a static IP, but i've set up an accout with no-ip.com and made a host etc etc. installed the software etc etc.
I've opened up the port 3389 on my router to my laptop i want to connect to (correct?)
Checked that the port was open and yes, it is..

now, when i jump on my other laptop and try to connect, i type in dreamflyer.no-ip.org which is my address i set up, but it comes up with an error and says make sure the remote computer is turned on and connected to the etwork ad that remote access is enabled.

HOWEVER, i can connect between laptops within our home network..
HELP!

It seems like you've done most of the setup correctly for remote desktop access, but you're encountering an issue when trying to connect from outside your home network. Here are a few things you might want to check or adjust:

Troubleshooting Steps:​

1. Firewall and Windows Settings:
   • Ensure the Windows Firewall or any third-party firewall software on the target laptop isn't blocking Remote Desktop connections.
   • Make sure that Remote Desktop is enabled on the target laptop. You can do this by:
     • Right-click on "This PC" or "Computer," then go to Properties.
     • Click on "Remote settings" or "Remote settings" on the left pane.
     • Ensure that "Allow Remote Assistance connections to this computer" is selected.
     • Check under the Remote Desktop section that "Allow remote connections to this computer" is enabled.
   []Dynamic DNS Update:
   • Check if your dynamic DNS service (like no-ip.com) is updating correctly with your changing IP address.
   []Router Port Forwarding:
   • Confirm that port 3389 is correctly forwarded to the internal IP address of the target laptop.
   • Sometimes routers have an option for "DMZ" (demilitarized zone), which you can try enabling for the target laptop's IP address. This effectively forwards all incoming traffic to that specific device, which can be a temporary troubleshooting step.
   []Confirm External Access:
   • Test remote access using a smartphone with cellular data (not using your home Wi-Fi) to ensure you are truly outside your home network when attempting to connect.
   []Security Software:
   • Disable any security software temporarily to see if they are causing the connection issue.
   []Network Configuration:
   • Confirm that your ISP doesn't block incoming port 3389, as some ISPs restrict certain ports for security reasons.
   []Update Dynamic DNS Client:
   • Ensure that the dynamic DNS client on your router is correctly updating your IP address with the dynamic DNS service. Sometimes, routers have built-in support for dynamic DNS services like no-ip.com, so you might want to check that the router is able to update the IP correctly.
2. Client Connectivity:
   • Make sure you are using the correct Remote Desktop client software on the connecting laptop and that it is updated to the latest version.

     Updates and Connections:​

     It's possible that there might have been changes in the network configuration or software updates that are affecting the remote desktop connection. By going through these troubleshooting steps, you should be able to isolate the issue and resolve it. Let me know if you need further assistance!
