So how about providing some more information about your hardware
disposition? And also the connection string that all of the client
application instances use.

The host machine has the Firebird server and the Firebird data file on
it. One user on the host machine runs an application that connects to
the database. One user on one client machine (connected to the host
machine peer to peer) uses one application to read data from the host
computer. The protocol using IB Objects is set to cpLocal for all
applications. Until everything on the client machine had to be
reinstalled, everything had worked fine for years.
