SYMPTOMS
Consider the following scenario:
 * You have a Web page that uses a Common Gateway Interface (CGI) in Microsoft Internet Information Services (IIS) 6.0.
 * The Web page in IIS 6.0 is running on a Japanese version of Microsoft Windows Server 2003.
 * A client computer sends a request to the Web page. The request includes an HTTP header that contains invalid data in a multibyte character set (MBCS) string.

In this scenario, the W3wp.exe process stops responding.

This problem also occurs on an English version of Windows Server 2003 that has the Language for non-Unicode programs option set to Japanese in Regional and Language Options.
