SYMPTOMS
========

Internet Information Server (IIS) may generate an Access Violation error message
in the Inetinfo.exe process when you request a URL with a DBCS trail byte that
is truncated.

CAUSE
=====

The URL with a DBCS trail byte that is truncated can cause heap corruption and
eventually cause intermittent IIS Access Violation error messages to occur.

RESOLUTION
==========

A supported fix is now available from Microsoft, but it is only intended to
