256986 Description of the Microsoft Windows Registry

When you submit a document to Microsoft BizTalk Server 2002 Service Pack 1 (SP1), the document is not delivered. An entry for the document is created in the suspended queue that contains the following line of text:
"This document is at following location:"No location is specified. You cannot recover the document.

CAUSE

This problem may occur if the file that is named Cdosys.dll is not registered on the BizTalk Server computer as the library file that provides functionality for the CDOMessage class. Under certain circumstances, the setup routine for other products registers the file that is named Pkmcdo.dll or the file that is named Cdoex.dll as the library file for the CDOMessage class.

To determine the file on your BizTalk Server that is registered as the library file for the CDOMessage class, follow these steps:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To start Registry Editor, click Start, and then click Run.
Type regedit, and then click OK.
After you start Registry Editor, locate the following registry key, and then check the value for the Default entry:
HKEY_CLASSES_ROOT\CLSID\{CD000001-8B95-11D1-82DB-00C04FB1625D}\InprocServer32

The value should point to the \WINNT\System32\Cdosys.dll file in Microsoft Windows 2000 or to the \Windows\System32\Cdosys.dll file in Microsoft Windows Server 2003. If the Default entry for this key points to a file that is other than Cdosys.dll in the location that is specified, note the location of this file and then follow the steps that are described in the "Resolution" section of this article.

RESOLUTION
