Having trouble with MOUNT *NFS

I am attempting the following command:
MOUNT TYPE(*NFS)
MFS('RMTSYSTEM:/SharedFolder')
MNTOVRDIR('/LocalFolder/Mark/')

I receive error:

Message ID . . . . . . : CPFA1CE Severity . . . . . . . : 40

Or, refer to the getaddrinfo() API in the Socket programming topic

- The target system name is in the hosts table (I can PING it), and I get the same error if I use the IP address.

- /SharedFolder is a share on the remote (Windows) system.

- I can view the directory using Windows Explorer.

- /LocalFolder/Mark/ exists on the local IFS.

Can this be an authority issue? It would seem to be that it didn't get that far, since the message seems to indicate that it can't locate the server.

How would a user ID and password get passed to the remote server?
