If you are using COM+/Enterprise Services components that talk to resource managers like Oracle or other XA RM, on Windows Server 2003 you need to make some additional steps to allow this scenario to work. This is due to a security change in MSDTC that requires you to register the XA DLL in registry. See more details at http://support.microsoft.com/?id=817066|||This is on 2000 AS.
