dll - fuslogvw -- could not load file or assembly on server

Question

I'm trying to invoke an Dynamics AX AIF inbound port (service) on a development server from my laptop using wcfTestClient. Because customErrors = Off, I can see the error message and it says it couldn't load an assembly.

I've set fuslogVw on the client and server. The client shows me a bunch of DLLs, but not the one that is throwing teh error.

I've set fusLogvw on the server as well, but it doesn't log anything.

How can I capture the DLL load details on the server?

Thanks.
