Q195894: XADM: Access Violation While Processing Long DBCS BinHex Files

Article: Q195894
Product(s): Microsoft Exchange
Version(s): 5.5
Operating System(s): 
Keyword(s): exc55sp2fix
Last Modified: 04-MAR-2002

-------------------------------------------------------------------------------
The information in this article applies to:

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


SYMPTOMS
========

An access violation error happens when processing long double-byte character set
(DBCS) attachment files, which are encoded in BinHex format.

CAUSE
=====

The current logic assumes that if a leading byte is found, the trailing byte
must follow. However, the trailing byte is removed because of shrinking long
attachment file names, and then the access violation happens.


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:
