>Sorry Eric,
>But what is the MTS ?

MTS (now COM+ in Windows 2000) is a server-sided software that will run/pool your ActiveX DLL components. MTS is also covered by the 1016 course I already refered to you. See this link: http://www.microsoft.com/com/tech/mts.asp

>>User access what? Database must be placed in a shared location but the application can/must be deployed to every user workstation (or else you need an Internet solution).

>>You can have components (ActiveX DLL or EXE) that runs on a server that are accessed through DCOM or you can install MTS on your server and install your DLL components in it.

You should consider having courses on that subject (see http://www.microsoft.com/trainingandservices/syllabi/syllasearch.asp?PageURL=/TrainingAndServices/syllabi/content/1016Afinal.txt for a good course on that)
