Thanks for your response! One salient point that I left out of my
initial description was that this problem was seen after a power outage,
which affected out entire local network. I actually have two AIX boxes
that are experiencing the same startup problem, which is why my initial
   suspicion was also that it was either NFS or DNS related. I have
tried both of your suggestions, but neither has had an effect.

Is there any other configuation data I should check to make sure neither
NFS or DNS is the culprit?

Cheers,
Dave
