D(istrobuted)COM is an sort of extension of COM created on the base of COM to make it possible to use te COM princaple thru an Network.
DCOM was renamed to COM+ when MTS (microsoft transaction server) was introduced.

Actually one of the main reasons MS came up with .Net was to get rid of COM, as COM is one of the reasons there are so many Buffer Overflow Exploits in windows (due to lazy programmers).
But because there are still so much legacy COM app's out there MS was forced to support COM under .Net.
But it will phase out eventually, but when? Nobody knows

MTS was the latest addition to the COM technology, which can be used to created packeges of COM+ components that can cooperate as one component.
