I was running OS X 10.6.8 Server on a mac mini and decided it was time to upgrade. I upgraded to OS X 10.10 and then installed Server 4.0.3. The upgrade went great no issues everything is working and kept all settings. However now it seems that my Windows 7 and 8 machines cannot access the shared folders on that Mac, all my Mac systems can access them just fine. I have checked and SMB is enabled, and when I go to connect from a Windows system it pops up with the credentials window and none of the usernames or passwords work? Has anyone ran into this?
