Semelhante a esta pergunta do SU: link
Na verdade, é praticamente o mesmo problema básico. Eu passei por esse thread tentando encontrar uma solução, eu mudei meu resolv.conf:
before:
domain [my work domain]
search [my work domain]
nameserver [my network DHCP]
nameserver [my network DHCP2]
Eu mudei para:
after:
domain [my work domain]
search [my work domain]
nameserver 8.8.8.8
nameserver 8.8.4.4
No entanto, sempre que reinicializo o computador, o resolv.conf é sobrescrito para a versão anterior (o 'antes' acima). (também não resolveu o problema)
Os problemas começaram depois que eu instalei adições virtualbox (AKA em uma nova instalação e após a instalação do Samba funcionou na internet e minha rede interna perfeitamente), servidor X e (especificamente) LXDE:

O adaptador no VBox é um adaptador em ponte diretamente na minha conexão ethernet; como são minhas outras 2 VMs (que funcionam)
