The Nvidia Mental Ray Satellite Service listens for control commands on port 7414. When it receives the command to load a DLL (via an UNC path) it will try to connect back to the host on port 7514. If a TCP connection is successful it will then attempt to load the DLL. This Metasploit module has been tested successfully on Win7 x64 with Nvidia Mental Ray Satellite Service v3.11.1.
