Answer:
The NT code 0xc002001b, indicates RPC_NT_CALL_FAILED (The remote procedure call failed.) This indicates the RN150 was able to communicate with the remote server however the remote server failed to complete the request. (RPC is used by programs, typically on a client computer, to execute a program on a server computer.)
