SYMPTOMS
If you follow the instructions in the Microsoft BizTalk Server 2002 SP1 Readme.htm file to register the CDO System Library (Cdosys.dll), you may receive the following error message:

DllRegisterServer in cdosys.dll failed. Return code was: 0x800704da

The return code 0x800704da is described in the Winerror.h file. This return code translates to &quot;The service is already registered.&quot;



CAUSE
This problem occurs because the Cdoex.dll file is already registered on your computer that is running BizTalk Server as the file that provides functionality for the CDOMessage class.



RESOLUTION
To resolve this problem, follow these steps:  Unregister Cdoex.dll. To do this, type the following command at a command prompt, and then press ENTER:

Regsvr32 /u cdoex.dll

 Register Cdosys.dll. To do this, type the following command at a command prompt, and then press ENTER:

Regsvr32 cdosys.dll

 Reregister Cdoex.dll. To do this, type the following command at a command prompt, and then press ENTER:

Regsvr32 cdoex.dll





STATUS
This behavior is by design.
