My first guess is that something in your resolving infrastructure is now treating .local special whereas before it didn't. The other option would be that some mDNS package got installed. You could look at the update logs since the last known previous state and see if something sticks out. That is, if you want to find out what happened as it seems to me that you fixed the immediate problem. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
