We have been having issues with our users getting the error stating that, "You don't have permission to edit the element until User2 saves to central and relinquishes." This error will occur on User1 machine even though User2 did not even touch the element in question. I had an issue today where User1 tried to modify an element, but an error occurred stating that User2 had control. User2 saved to central, relinquished, and closed the project. Revit then allowed User1 to modify the element, but then User2 reopened the central, saved as a local, saved to central, but then Revit stated User1 had control of the elements once again. We have had many problems with this lately, where it'll say UserX has control, even though UserX has not touched the project. I have looked through the forums and came across the user name issue, but we are a firm that does not share workstations. The user name that appears is the same that will appear on every project, we do not modify user names. We then get into a circular chain of trying to STC and relinquish, but then it gets to a point where nobody can open their local file or even the central file. We then have to revert to a backup file off the network, which usually equates to lost work.
