The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

If you send a message labeled with a code page 0 character set (such as US-
ASCII) to a computer running a double-byte character set (DBCS) version of
Microsoft Exchange Server, a general protection fault (GPF) may occur on the
Exchange Server computer.

CAUSE
=====

When a code page 0 message is sent to a DBCS Exchange Server computer, the
message may contain incorrectly aligned characters after it is processed by the
server. This may cause a buffer overflow to occur, which can cause a GPF to
occur on the server.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5. This problem has been corrected in the latest U.S. Service Pack for
Microsoft Exchange Server version 5.5. For information about obtaining the
Service Pack, query on the following word in the Microsoft Knowledge Base
