    Port 9001 is not available


    I have to run some development server on port 9001, but 9001 is in use by the SYSTEM process. How can I make it stop doing that? This has started happening since yesterday, and I have completely shut down and freshly booted up my laptop in between then and today.


    Even with something like Process Hacker I cannot figure out which process other than SYSTEM is responsible for keeping this port open. Also when I open it in my browser, e.g. http://localhost:9001/, I just get a 404. Diving into its HTTP Response headers, I see the Server header is set to "Microsoft-HTTPAPI/2.0". That is NOT something I started, so it must be a system thing which, strictly speaking, it is.


    How do I free up this port?

    :)

    Then select the standard driver from the list and click next:

    Click next/OK as required to complete installation. Repeat the steps for all Intel USB devices. Finally click on each USB root device and press DEL to delete it, reply YES when asked. After deleting all USB root devices restart the computer.

    I hope this is detailed enough...

    Port 9001 is not available

    Port is being blocked

    Hi,



    Thank you for writing to Microsoft Community forums.



    • Are you aware of any changes that happened on the computer prior to this issue?


    Upon researching, this seems like an issue due to the port scan. You may want to try the steps listed below and check if it works.

    • Login to your Netgear
      NX6200 Extender GUI      .
    • Click on Advanced tab and choose
      WAN Setup      .
    • Check the box for Disable Port Scan and DoS Protection.
    • Allow it to update and check if the port is still being blocked.


    However, if the issue persists, I suggest you to post your query in the
    TechNet Forums, where we have support professionals
    equipped with knowledge on port forwarding.



    Regards,
