IT is FIXED - Thanks folks.
We upgraded the firmware on our network switch cards this past weekend. The settings on this and one of the nfs servers' port were
reentered wrong.
Back to Auto-negotiate at both the network port and the two RS/6000 and all is GREAT again.
Thanks once more.

if you can check the switch port he's on, make sure it agrees in terms
of speed/duplex with what the aix box thinks it's set to. you can check
on the switch for errors, as well.
