In 'Workgroup Manager' the 'Sharing' is greyed out in both the menu and tool bar. This had happened while having version 10.3.5. Upon finding this I updated to 10.3.8 in hopes it would fix the problem. It didn't.
I repaired permissions and did the disk repair but still no change.
This ticket has been moved to the open forums for more exposure.
