Any Mac on my business network could not maintain it’s connection to a share on a Windows 7 based pc. They would randomly disconnect. In order to reconnect the Windows 7 PC would have to be restarted. Alternatively, a restart of the server service also rectified the problem The issue seemed to be more prevalent whenever large files were being copied to the shared folder.

Event ID: 2017
Level: Error
