What do the `host' or `dig' utilities say if you try to resolve a
host name on the non-working computer?
You can also call them with a nameserver they should use (but this
shouldn't necessary if resolv.conf contains the correct nameserver):
$ host [hostname] [dns server]
$ dig [hostname] @[dns server]
Did you try resolving the full host name (e.g. myhost.example.com) or
just the first part (e.g. myhost)?
