This fact may be related as the .local domain is used (reserved?) for
Avahi and mDNS.
On Fedora, my /etc/nsswitch.conf file has the following:
hosts: files mdns4_minimal [NOTFOUND=return] dns
I expect Ubuntu's is very similar, so if the mdns lookup fails the
entire host lookup will also fail. You could probably move
mdns4_minimal to the end of the line, so your DNS takes precedence:
hosts: files dns mdns4_minimal
This might affect Avahi though, but if you don't care about it just
remove or disable the Avahi services entirely.
Or the best solution might be to change your internal domain sooner
rather than later! There are a few domains and TLDs reserved for
internal use:
