Your dns setup is wrong somewhere, it does not seem to be able to find 
the laptop on the first nameserver in your /etc/resolv.conf so it is 
then trying the internet

This is what I did to my Mint laptop:
/etc/resolv.conf is set by the resolvconf package
changed /etc/nsswitch.conf dns line
edited /etc/hosts, adding the domain name
edited /etc/NetworkManager/NetworkManager.conf and commented out the 
dnsmasq line

That is it, and it works for me, although my updates are done by DHCP 
and script on the server.
