Dlls on the server for thin client

Hi all,

My VB program has dlls (our own, VB's and 3rd party's products'). Normally on the NT environment, I have to install almost every dlls on the client and register them if needed, only leave db on the server. Can I put most of the dlls on the server drive and leave client as thin as possible? What dlls I have to intall and register on the client normally (ADO, DAO, DCOM, etc)? Thanks.
