SYMPTOMS
========

NOTE: On Sunday, February 23, 1997, Microsoft was alerted to a posting regarding
an Internet Information Server (IIS) security exposure. This bug permits the
publication of IIS executable files via a complicated string of commands sent
from a web browser to an IIS server.

Because of this security exposure, Internet users can view Active Server Pages
(ASP), Internet Server API applications (ISAPI), Internet Database Connector
(IDC) applications, or Common Gateway Interface (CGI) applications within an IIS
publication installation.

==========
