NFS has the following good properties:
- correct user management (different users have different rights on
different directories
- no problem exporting most file systems (reiser can be exported over
NFS with  no problems - doing it on all my servers)
- if well-configured, very fast. If running a mixed-speed network, it is
advisable to use "-o tcp".
- a reboot of the server gives no problems. The client will normally
wait until the server is back (and give some warnings like "server not
responding" in the log in the mean time. 
- NFS is native unix/linux

- Samba easy to setup - in limited usage models
- Samba tends to be efficient on the wire
- samba does not support different users on the same computer. All
shares mounted on the same computer are supposed to have the same user
and user permissons (and especially supposed to have the same user
password). This last one can be a bit difficult when mounting to
different computers. 
- samba can be merry hell to setup over different servers/networks - i
still have it not working well when operating over several subnets :(
- Samba is native windows, linux support is re-engineered (though very
well done). This does mean it's target is interoperability between
linux/windows and not so much sharing between unix/linux machines. 

With respect to the original query, i simply do not have enough
information to make a guess on what is going wrong. And as i am not
using ubuntu, it is difficult for me to make guesses at the setup. 

Cheers,

Rudy
