You weren't clear if the "Clients" are just several threads in a
single Process, or seperate Processes.

Each Process must load the DLL. Each instance will have it's own copy
of the DLL's data.

Multiple Threads within a single Process can access the same instance
of the DLL. They will share the DLL, and all of it's data.

As to "conflict", that depends on what sort of conflilct you are
concerned about, and how the DLL was written.
