SYMPTOMS
A third-party service may quit unexpectedly on a Microsoft Windows Server 2003 64-bit edition-based computer when the following conditions are true:
 * The third-party service runs as a 32-bit process.
 * The third-party service calls either the GetFileType function or the GetStdHandle function.



CAUSE
This problem occurs because the process environment block (PEB) of the 32-bit process has become corrupted. This corruption causes the service to return FILE_TYPE_UNKNOWN to Microsoft Windows on the 64-bit operating system. Windows on 64-bit operating systems is a 32-bit Windows subsystem that you can use to run 32-bit programs on 64-bit versions of Windows.
