You could then leave the two backups in /etc/resolv.conf but if your=20 local nameserver is authoritative for your local domain, then you=20 probably want to know if it goes away, and those backups won't be able=20 to look up names in your local domain. I'm making some assumptions about why you set things up this way in the=20 first place, and I may be wrong, but there's too little info in your=20 post to give definitive suggestions. --Alex
