This happens when the system is configured to use DHCP or NWAM.  You
should probably google those terms and read up on them.  I somewhat
suspect NWAM here.

By default, the system comes set up for *automatic* network
configuration, so that you should be able to plug it in and just run
with it without hassle.  If you really want to set up static network
configuration instead, you have to jump through some hoops.  I'd start
with this:

svcadm disable svc:/network/physical:nwam
svcadm enable svc:/network/physical:default

I can't recommend that as a great solution for everyone ... but if
you're bound and determined to do static configuration, it's a start.

That nails it as a name resolution problem.

Yes; just disable the automatic configuration services.

As has been noted several times before, you MUST make sure that
/etc/nsswitch.conf is set up to use DNS.  Or go through one of the GUIs
or SMF things that does this for you.  (Frankly, I grew up with UNIX
systems, so the idea of using some sort of tool to do it rather than
editing the configuration files seems a bit weird to me, but do whatever
you feel comfortable with.)

Looks like you're configured to get name service from yourself, and
that's not going to work unless you're running a name server on this system.
