Thanks Neil but I looked at that also. My exports file looks like
this....

/somedir (rw)

Allowing anyone to connect. Also my hosts.allow is...

ALL: ALL

Allowing everyone also. Right after the new box comes online 
and fails(when it worked with a different hostname). Something
gets corrupted in nfs. No matter what I do, nfs will not work.
I have tried replacing binaries ( rpc.* )with no avail.

Could it be stale clients that were not unmounted before the switch?

Thanks....

At a guess, I would say tcpwrappers problem.  Maybe you have to old
host-name in /etc/hosts.allow, or something like that??
