Limiting a program to only have one instance

    We have a program running that is set to a number of liscences and once this is reached it will lock out everyone else.

    So I'm looking some batch file or program that restricts any PC to only opening 1 instance of this program, If it happens to restrict all programs to only having one instance, so be it.


    Any recommendations?

    I'd love to have something like that where you install the program on a shared folder and only one user is allowed connect at a time.

    Even if anyone knows about a terminal server setting to do that.

    You could have batch files - but they could be bypassed by going directly to the program.

    [php]
    if exist x:\lock.txt goto :inuse
    echo %date% %time% %username%>x:\lock.txt
    start /wait program.exe
    delete x:\lock.txt
    goto :done

    :inuse
    type x:\lock.txt
    :done
    [/php]
