   I'm coming to this thread way late, but better Nate than lever....

   If you've exhausted all the basic prospects, probably the next thing 
I'd do is an rmtcpip and reboot.  That (assuming 3.2 *had* rmtcpip; I 
don't have a 3.2 box or docs available) unconfigures everything 
including the interface.

   AIX pre-v5 is really bad about retaining ghosts of previous network 
configs if they're not reconfigured in exactly the right procedures. 
It's possible to track all that down, but just whacking everything and 
starting clean is much easier.
