I've had to clean a number of these up. The worst is when "foobar.com" answers with a wildcard record. Booting client computers using public DNS in that scenario is like being stuck in a tar pit. The poor helpless operating system tries and tries to reach servers to query for its AD site, find Domain Controllers, apply group policy, run scripts, etc.
Microsoft's official training curriculum for "MCP" and "MCSE" back in '99 was pretty clear about it (I was an instructor at a community college for a Microsoft certification program), but other Microsoft docs and especially third-party docs weren't as clear. Thr whole ".local" debocle with Windows Small Business Server lays at the feet of Microsoft, though.
