We have (2) PC's running auto Windows Update which have Network drive maps to an Apple network file server. After the patch yesterday, after reboot, neither machine could see their existing mapped drive to their primary Apple file server. The drive maps had broken, and in order to reestablish them, the i.p. address (for instance \\10.1.10.1\appleServerName ) had to be entered. Other Linux and PC devices were unaffected. A few other Apple machines were still visible, but they no longer accepted logins. What gives? Is this Apple or their local admin failing to update their system to the latest patch? They immediatley blamed Windows, mocking and smirking that 'they' did nothing, Windows just broke. I can't find any info in the patch notes about this.. Maybe someone can explain please. Thanks
