I don't know if your .local domain is part of this problem, but I've personally seem that cause a load of other problems with Macs. So much so, now I wouldn't touch a .local domain with a 10 foot pole when it comes to Macs. Been there, done that. Never again.
That said, you don't have the Macs set to prefer the domain controller that died do you? That is an option and could certainly cause problems. Otherwise, I have never seen Macs have a problem with a missing AD server. Of course, your DNS may be completely stuffed and that could be causing it as well.
I strongly suggest diving into the console after logon failures (with a local user) and searching for the username that failed to logon. You should learn quite a lot about the cause of the problem that way. And of course, check DNS resolution to your servers.
