unable to communicate with specific ports RRS feed

  • Question

  • I have a proprietary Software application  for  running a flight simulator.  it is  working fine  in windows xp pro 32bit. It uses UDP Ports nos: 5000, 6000, 17001,9001,11180,18001 to communicate with other PCs in the Local Lan to communicate with switches(anolog & digital) & the controls. but, now the same application does not comminucate on running the application in windows 7 pro 32bit service pack1 . The application simply shows up in the desktop with out any response. I have switchoff the firewall, i 've also made the application to  run in winxp srv pack3 compatible mode, and also tried to run in administrator mode. There is no joy. any suggestion will be appreciated.

    Thanks

  • Try running TCPView to check for any programs using the ports.

    You can download TCPView from the following link:

  • Thanks Mr. Balaji Kundalam,

    I've tried a similar software to TCPView, CurrPorts v2.20 Web site: http://www.nirsoft.net. but no ports are being used.Secondly the problem is my application does not show up at all in CURRPORTS screen, when run on a win7 32bit but it shows with all the ports open on a win xp32bit pc. I will also try TCPView now

    Thanks

    Rashid D.

  • Hi reshiddawood,

    Thank you for your question.

    First of all, we suggest you contact the vendor of software to make sure it could be supported on Windows 7.

    When you install it, please check if the post has been used for this specific application by TCPView, you could use the following command: netstat –an.

    Best Regard,

    Jim Xu

    Jim,

    I think the command is netstat -an and not netsate -an.

    Correct me if I'm wrong.
