First of all, thank you for the suggestions so far...

I have removed the nis entry from nsswitch.conf, but with no luck.


I'm quite frustrated by this. I have tried to provide all the
information anyone might need to diagnose this problem... I'm sure the
solution is very simple, but I just don't know hpux well enough. And I
have not been able to find any good answers in the admin manuals I have
downloaded; perhapse I am looking in the wrong place.

Will this help anyone?

SUMMARY

My computer has access to the local LAN. It has access to the internet,
and can see my Domain Name Servers and even Yahoo.com when asked via IP.
I have a sane routing table (afaik), but cannot add a new route. It
seems as though hpux simply does not know to use the DNS servers to
resolve domain names.

Thank you again for any help you might provide,
