    The best thing an IIS admin can do (other than patching their system) is
    to remove the 'blank' host header. The default settings of IIS 4.0, 5.0
    and 5.1 allow the server to answer to the IP of the local server. If
    they remove the blank host header they are forcing the host header to
    match something listed in IIS.

    After the last Code Red I wrote an article that Brett Hill posted at

    Thanks for the heads up!
