You are right. Npfs returns the wrong status.

Not necessarly, sometimes the client must interpret ERROR_PIPE_CONNECTED as a success:

"If the specified pipe handle is in nonblocking mode, ConnectNamedPipe always returns immediately. In nonblocking mode, ConnectNamedPipe returns a nonzero value the first time it is called for a pipe instance that is disconnected from a previous client. This indicates that the pipe is now available to be connected to a new client process. In all other situations when the pipe handle is in nonblocking mode, ConnectNamedPipe returns zero. In these situations, GetLastError returns ERROR_PIPE_LISTENING if no client is connected, ERROR_PIPE_CONNECTED if a client is connected, and ERROR_NO_DATA if a previous client has closed its pipe handle but the server has not disconnected. Note that a good connection between client and server exists only after the ERROR_PIPE_CONNECTED error is received."
