mount: RPC: Program not registered

Hi Group,

Recently i deployed one NFS server(S1) with three clients(C1,C2,C3),
two client nodes successfully mount NFS server(S1) share into local
directory , but problem with client3 , when i tried to mount NFS
Server(S1) share directory in to local directory , it showed the
error message 'mount: RPC: Program not registered'.

# mount -o rsize=8192,wsize=8192 S1:/remote /local
mount: RPC: Program not registered

To minimize the complexity i add following line in /etc/hosts.allow in
NFS server(S1)

portmap:ALL


RHEL ver 3.0 installed on all machines.

What is in the /etc/exports on S1? Are you sure C3 is also allowed to
nfs to it?
If yes, do you see anything to indicate that a connection was attempted
from C3 in /var/log/messages on S1?
