I upgraded our workstations to Windows 10 Pro. I back up 3 of the workstations with Retrospect, but last nite only one of them worked. When I looked at the logs, the two that didn't said Error -1102 drive missing. When I load the client on the server, it can talk to the client software, but if try to access subvolumes in the Volumes screen, it can't access the client hard drive. The one client that worked has no issue accessing the hard drive in the volume screen.
Anyone have any idea why one would work & the other two don't? All worked on Windows 8.1 before the upgrade.
