A "workstation install" is not the same as running the application off the local drive. The local workstations should be loading the EXE from exactly the same location as all the other users, and all their drive mappings must be consistent, at least as far as the drives letters used to find the Adagio applications and the data.

We have seen many successful Adagio sites use a strict Terminal Server configuration (where everyone accesses the modules through Terminal Server, whether or not they are local). It works fine.
