Two machines same problem w/ NFS

[Susan Champigny]

I have one 64 bit machine running 2.6.9-5ELsmp kernel
the other is a 32 bit running 2.6.9-1.667.smp.  Both are having
the same problem. Both these version have SELinux wrapped up in the kernel.
I am trying to mount home directories from my nfs server.  I get the 
following
error

mount to NFS server "machine" failed.

On other hand I can nfs mount from another machine, so I am quite baffled.
Can anyone shed some light?

The home directories are exported and both machines can ping each other.

Sue
