I've had the same problem with some of our Suns. It turned out, that
these Suns had more than one network-interface (and different names
for the interfaces). It seems that linux is only able to mount from
the first interface on the way to the specified host. So if machine
foo is in Subnet A, machine bar in subnet B and machine foobar on both
(gateway) with names foobar-a for interface on subnet A and foobar-b
for interface on subnet B, machine foo can mount foobar-a, but not
foobar-b and machine bar can mount foobar-b but not foobar-a

        foo bar
         | |
 A-------+--------+- B-+---------+------------
                  | |
                 foobar-a foobar-b
                       ^ == ^

foo can mount from bar and the other way round.
The same problem existed (I believe) with PC-NFS 3.0, but not with
4.0.
