I'll consider doing that.  I was just reviewing your previous
responses.  Is it correct to say that resolv.conf should contain the
dns and domain information?  I thought I had read way back that ubuntu
no longer used that file.  If it should be populated with that info,
then it is curious that it has been deleted three times.  We know I
don't have DHCP running, so what else would delete the contents of
that file?
