I think of database server as the actual software installation together with all the dll and other files which are shared by multiple server instances. Each instance though is a seperate entity in terms of its components and environment but they do share the same files eg: dlls hence called instances of the server. Correct me if i'm wrong. regs savio >From: "Mark D. Stock" <mdstock@mydas.freeserve.co.uk> >To: "Stephen F.
