    I may be laughed from here to kingdom come on this listserve...but I
    gotta ask....

    Common best practices for whom? Define a role please? What is "common
    best practices" may not be good enough for one person, but may be just
    fine for another. What are they doing with this box? Exposing it to
    the web as a web server...yeah I'd still argue that's insanity.

    But Small Business Server 2003 runs with IIS on our domain controller.
    Where's MY security risks these days? Not my server..nope......it's my
    desktops where my security risks lie.

    Port 80 is closed on my server but IIS is still on there. On the
    outside is Firewall, intrusion detection and what not. Running with XP
    sp2 firewalls on the inside but still need to get to more use of user
    mode on the desktop.

    Am "I" freaking out over IIS on my domain controller? Nope. Not at
    this moment. Am I freaking out over admin rights on desktops?

    You betcha I am... big time.
