Transaction Server Type Library and Shared Property Manager Type Library are in COM+ Services Type Library in Windows 2000

The name of the type library that has all the COM+ ObjectContext, Object Control, and related functions and objects is "COM+ Services Type Library" in Windows 2000.

To be able to use ObjectContext to control transaction outcome and gather information about the execution context or to receive a callback on activation and deactivation or to use the Shared Property Manager in an early-bound fashion, you must set a reference to the COM+ Services Type Library. This is different than for Windows NT 4.0, where those libraries are called "Microsoft Transaction Server Type Library" and "Shared Property Manager Type Library."
