    Ladies and Gentlemen:

    I've got an odd problem. Our library needs certain ports open on our
    firewall - we're using ISA 2K.

    When I create a protocol rule to open those specific ports, it doesn't work.
     When I open the firewall completely, it works. When I open all ports except
    the ones in question, it works.

    The protocol is Z39.50 - apparently it's used quite a bit in library
    applications.

    I've looked at our protocol rules - everything seems in order. And other
    libraries have their firewall configured in this fashion.

    Help!
