I understand that I need exclusive access to make design changes. Is there a way to set a time limit and kick people out after a period of time. I work in an office and everyone minimizes the databases instead of closing them, some even leave it minimized over night. (I do ask them to close it) If I need to make any changes I have to go around and check everyone pc, and if their pc is locked, the only way to get them out is to reboot. I usually work on a copy of the database and export updates but I donâ€™t think its very efficient when I have to update a dozen queries and reports.
