He has no nameservers listed, so unless he is running a local 
nameserver (bind, etc.) he can't resolve any names.  See `man 
resolv.conf`, the second paragraph and the "nameserver" section.

This is (most likely) happening when his DHCP lease is renewed and 
something doesn't work.  There might be a log (perhaps
/var/log/messages) where PPP mentions such things.
