WTF? RPCPROG_NFS: RPC: Program not registered

[Ronald F. Guilmette]

I have a 9.1-RELEASE server whose /etc/rc.conf file contains, among other
things, the following lines:

ifconfig_nfe0="inet 192.168.1.2 netmask 255.255.255.0"
#
nfs_client_enable="YES"
nfs_server_enable="YES"
nfs_server_flags="-h 192.168.1.2"
mountd_enable="YES"
rpcbind_enable="YES"

On this server, I also have an /etc/exports file that contains:

/home/rfg -network 192.168.1.0 -mask 255.255.255.0
/x -network 192.168.1.0 -mask 255.255.255.0

On this same server, when I do "showmount -e 192.168.1.2" I get the following
output:

   Exports list on 192.168.1.2:
   /x                                 192.168.1.0 
   /home/rfg                          192.168.1.0 


On this server, when I am root, I attempt to do:

    mount -t nfs 192.168.1.2:/x /mnt

but tnen I just get the following error:

   [tcp] 192.168.1.2:/x: RPCPROG_NFS: RPC: Program not registered

Why?

More to the point, what I can do to get rid of this error?

I really am stuck.  I have no idea what causes this error, nor even how to
debug it.  I have already google'd the hell out of the problem, and I am
still coming up empty.

Note also that when the failure occurs there is -nothing- added at that
time to /var/log/messages.

P.S.  Of course, I don't actually need to mount the exported volume onto
the same machine where it physically already resides.  I do however wish
to mount it (via NFS) onto another system on my LAN, and over on that other
system, when I try to mount it, I am getting the exact same *&^%$#@ error.


P.P.S.  In case anybody should ask, this is the output of rpcinfo 192.168.1.2:
