Using .local for your LAN and putting mdns4_minimal before resolve and dns is probably part of the issue. mdns4_minimal is probably intercepting the query. What it does with it is anyone's guess.

You could try changing the order in nsswitch.conf but long-term, try using a different TLD for your LAN. IANA recently proposed using .internal for that. (I've been using .lan after my company name.)

Thanks. I simplified nsswitch.conf to just "host: files dns" and the problem seems to be resolved. (Time will tell.)

Changing the TLD will take some time and care but that seems like a good idea. Thanks!
