The W3wp.exe file that is used to create and to publish to the Web in Exchange Server 2003 SP1 crashes after you input your user name and password in OWA

When you use Microsoft Outlook Web Access (OWA) to open a Microsoft Office Excel 2003 file that is attached to an e-mail message, you may be prompted for your user name and your password. When you press ENTER after you input your user name and password, the W3wp.exe file that is used to create and to publish to the Web in Microsoft Exchange Server 2003 Service Pack 1 (SP1) crashes.

This issue occurs when Korean and Chinese character codes are mixed and used on the same page. When the URL for an attached file that is made up of multibyte characters in different code pages is transferred to the Davex.dll file, the file crashes the Web working process (w3wp.exe) executable file.
