What is ES.dll?

COM+ is an evolution of Microsoft Component Object Model (COM) and Microsoft Transaction Server (MTS). COM+ builds on and extends applications written using COM, MTS, and other COM-based technologies. COM+ handles many of the resource management tasks that you previously had to program yourself, such as thread allocation and security.

About ES.dll (from Microsoft)

“COM+ also makes your applications more scalable by providing thread pooling, object pooling, and just-in-time object activation. COM+ also helps protect the integrity of your data by providing transac”
