On the NFS server try "rpcinfo -p" if you don't see output then you have
a portmap problem.

If that works you should see output like this:
  [ben at ben ben]$ rpcinfo -p mis-unix
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100011    1   udp   1008  rquotad
    100011    2   udp   1008  rquotad
    100011    1   tcp   1011  rquotad
    100011    2   tcp   1011  rquotad
    100005    1   udp  49525  mountd
    100005    1   tcp  48828  mountd
    100005    2   udp  49525  mountd
    100005    2   tcp  48828  mountd
    100005    3   udp  49525  mountd
    100005    3   tcp  48828  mountd
    100003    2   udp   2049  nfs
    100003    3   udp   2049  nfs
    100021    1   udp  49526  nlockmgr
    100021    3   udp  49526  nlockmgr
    100021    4   udp  49526  nlockmgr
    100024    1   udp  49527  status
    100024    1   tcp  48829  status

If you don't see the daemons above listed check /etc/init.d/nfs 
and /etc/init.d/nfslock to see why they are not running.

Then go to the NFS client machine and try "rpcinfo -p SERVERHOSTNAME"
you should see the same thing as above, if not then there is a
firewall/tcpwrappers issue.

If you see the same output on the client then do:
	showmount -e SERVERHOSTNAME

To see what exports are available.
If you don't see any exports then you have a problem with
your /etc/exports file, try re-running exportfs -a on the server.
