Имхо, а собственно на терминальном клиенте сборка есть?

"Assemblies that are used in a DAX application must have references in the AOT. If you have assemblies available to all clients then these assemblies should be installed into the GAC on each AOS servicing the clients (assuming that code using assemblies installed on the AOS runs on the server tier).
Alternatively, it is possible to install assemblies on each of the client machines but in this case you should make sure to install the assemblies in the same location on each machine, to retain the referenced location in the AOT.
In your case it seems that a corresponding assemly is either not installed on box "B", or it's installed in a location different from GAC and different from a location on box "A" (hence a location referenced in the AOT for the assembly in not valid on a box "B"), or it has no reference in the AOT at all."
