VSS is resuming it's sabotage of my repository again. The repair command won't let me repair, the lock VSS doesn't seem to affect currently logged in users-- and it isn't a user, its claiming the only person logged in is admin (via the VSS admin tool!) and I have already closed all instances of the VSS admin tool and client.
In computer management, close all the sessions and open files. It's drastic, but that is the only way I found to fix it. You also might want to close the share temporarily.
