What does your /etc/hosts.allow look like? Hopefully like this (with
the appropriate IPs substituted for my local and remote examples):

portmap: localIP remoteIP
lockd: localIP remoteIP
rquotad: localIP remoteIP
mountd: localIP remoteIP
statd: localIP remoteIP
nfsd: localIP remoteIP

You can try running this command in a terminal to verify your NFS
settings:

rpcinfo -p

This will give output like this:

program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100021 1 tcp 34117 nlockmgr
100021 3 tcp 34117 nlockmgr
100021 4 tcp 34117 nlockmgr
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100021 1 udp 32770 nlockmgr
100021 3 udp 32770 nlockmgr
100021 4 udp 32770 nlockmgr
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
100005 1 udp 777 mountd
100005 1 tcp 780 mountd
100005 2 udp 777 mountd
100005 2 tcp 780 mountd
100005 3 udp 777 mountd
100005 3 tcp 780 mountd
100024 1 udp 32771 status
100024 1 tcp 49870 status

If you don't at least see a line that says portmapper, a line that says
nfs and a line that says mountd, then you'll need to backtrack and try
again to start up the daemons.

You might need an NFS restart:

sudo exportfs -ar
sudo /etc/init.d/portmap restart
sudo /etc/init.d/nfs-common restart
sudo /etc/init.d/nfs-kernel-server restart

Or a network restart:

sudo /etc/init.d/networking restart

After the command runs, reboot the computer.

That's about all I've got diagnostic-wise. Hopefully you already had it
sorted. (:
