Recently moved all client machines to a sub zone of our top-level. All workstations workstations (dhcp/ddns) have fallen from cigital.com to dyn.cigital.com. Suddenly, none of the unix workstations are accessible by UNC, ie \\machine via Samba/NetBIOS. What gives? Is this the right forum for this question? Better place to ask? Ideas? -Yanek.
