Opening NT4 Ports...

    I haven't looked at NT4 for a while, so when I was asked today to make sure
    that a port (needed by an application) was open, I was stumped. I mean, I
    remember NETSTAT and running it it did not display any info about the port
    of interest, so my question is, "How do you open a specific port, on an NT
    server?"

    BTW, I googled for a while and found all sorts of obsure info regarding
    ports, but not an answer to the above question.

    TIA, to anyone that comes up with an answer.

  2. You "open" a port on a computer by installing a service (software) that uses
    that port. The port can be "blocked" by using a firewall and to allow the
    port to be used you "open" a port in your firewall.

    Do you have a firewall on the server?

    Thank you very much for the reply. No, there is no firewall on the server.
    They installed the application on 4 clients, and it runs fine, th eyn, when
    they tried the same on the NT4 box, the application does not run and pops up
    an error that the required port may be blocked.

  4. Someone mentioned yesterday that there is a text file in the system32
    folder, where one can specify the ports that are needed (opened) by a
    certain application. I was wondering if there is such a thing... It sounds
    too simple...

  5. I would verify that the program *will* run on NT server.

    In my experience *usually* you need one version to run on a server OS and
    another version to run on a workstation OS.

  7. Thanks. I'm just trying to figure out what would be locking down that
    specific port :-(

    That's the IANA well known ports list. That has nothing to do with what is
    open or not. Follow Dannys suggestion and make sure the app will run on NT4.

  9. That's what I suggested, as well, but the tech that was sent to install the
    application (I was not present at the time), insisted that he hast installed
    it on servers many times and this is a "locked port" problem.

  10. Thanks. I'll go back and ask them to make sure that the application is
    compatible with NT4.

    What port is the application listening on?

  12. I think it's either 9011 or 9012 (I don't have it in front of me right
    now).
