Impossible to open a port on Win 7

I tried specifically to open a port for RDP (3389) and I have it configured correctly, including router - for the transfer, but the port is still invisible.

I used online resources to check that everything is as it should be with parameters and compared the parameters of this dialog with others in my network and they are all identical (as far as I know), yet always the port is invisible from the outside.
No other ports are visible when open, and I tried with firewall off and no anti virus.
What could be the challenge with the ports of this box?
Appreciate all the comments and suggestions.
Name of the operating system Microsoft Windows 7 Ultimate
Version 6.1.7600 Build 7600

  • Impossible to open a port on Windows 7

    I have a mobile application that needs me to open the port 23424 on my system. I forward the port in my router and helped him. Then, I opened the port in the Windows Firewall. The app would not work. I put my system in DMZ, still no connection. I then unplugged the two firewalls, and again, I could not access the port.

    I checked on www.canyouseeme.org. and it reports "error: I could not see your service to the 76.xxx.xxx.xx on the port (23424) reason: Connection Refused" I then tried a new router, open port, the same thing. I can't understand what is blocking or refuses the connection. No matter what I do, something is obstacle in this regard.

    I have Time Warner cable and talked with them and we checked that their router is not active and acting as a bridge to my router. All other services are working properly, I can't just open this port.

    I use Windows 7 Home Premium, Microsoft Security Essentials antivirus software and a router Belkin N750.

    What Miss me? Thank you.

    You only need to run a firewall and not more than one firewall on your computer...

    PortQry message means that your problem probably is on the router, since you can connect with PortQry to this port from another PC on your LAN.

    I would check with the router manufacturers support site to help port forwarding...

    Check the status of the modem in Device Manager. You don't see any yellow exclamation?

    Check the operation of the Modem under
    Start-> Control Panel-> phone and Modem Options-> Modems tab-> properties-> Diagnostics
    by pressing the 'button interrogate Modem.

    If the information window about the Modem contains a list of COMMANDS (including ATI2, ATI3, ATI4 etc.), then the modem is installed correctly. The ATI5 command ends with the number for the parameters selected regional (for example Germany = 06).

    Follow the suggestions below for a possible solution:

    Method 1: I suggest that you scan your computer with the Microsoft Security Scanner, which would help us to get rid of viruses, spyware and other malware

    The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

    http://www.Microsoft.com/security/scanner/en-us/default.aspx

    Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

    Important: While running scan on the hard drive if bad sectors are found on the hard drive when scanning try to repair this area if all available on which data may be lost.

    Method 2: If this does not help then you can uninstall and reinstall Windows search 4.0 on the computer.

    Follow the steps below to uninstall:

    a. click on Start

    b. click Control Panel

    c. select Add / Remove Program

    d. place a check on "Show updates"

    First thing to try is a system restore:

    Try in Safe Mode, if it is impossible for normal Mode.

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...
