    If you are running Microsoft IIS, install URLScan and read the
    instructions.

    Subject: Preventing OS Detection

    If I go to http://uptime.netcraft.com and enter my website, Netcraft
    will display my web servers OS, determined from the TCP/IP packet. Is
    there a way in the windows registry to prevent Netcraft (or anyone else)
    from identifying my OS? On the page http://www.webhostgear.com/36,1.html
    in paragraph titled "Netcraft is Watching", it briefly describes that
    registry changes can be made. Can someone please give me some specific
    registry changes to prevent others from identifying my web servers OS?

    Thanks,
    Paul Kurczaba
