    Hi list, I think I resolved my issue!

    I was messing around with this machine yesterday and put it in a state
    where nothing would work ... ps and ls wouldn't work with messages
    about not enough memory. Same thing this morning, so I figured I'd
    reboot it ...

    Turns out that seems to have been the key. After the reboot this
    morning, this machine just came back. Network was still down, but when
    I did smitty tcpip, THE PROPER GATEWAY SHOWED UP (it's always showed
    the old gateway value after a reboot, that was the issue I was trying
    to address)! After verifying the settings and letting smitty run, the
    network came right back.

    I think I still have some kinks to iron out (it's not yet doing name
    resolution - BIND must have not been happy about being down for so
    long), but it SEEMS to have worked itself out.

    I can't thank you all enough for your patience and support, especially
    Hercom who made this sound so easy. I guess it didn't hate me after
    all, it just needed a short nap.
