I have a mulituser database where up to 10 users may access a .mdb at the same time, but usually on 2-4 are using it at any given time.  The .mdb is split with the forms, queries, reports, etc. on the user's desktop and the back end on a local server running Microsoft Server 2000.  The users all have full permissions to the folder where the back end .mdb is located.  There is no security on the .mdb itself other than Shift-Bypass.   The default open mode is shared.  The default record locking is set to  No Locks.  Open Databases with Record-Level Locking is enabled. The deskstops are running Windows 2000 and are using Office 2000 Professional.  The .mdb was created in Access 2000

I am expereincing a problem  that several times a day, users will become locked out by other users.  The lock out sometimes occur when the user locking the others out opens the .mdb and sometimes after the .mdb is open for a period of time.  One computer does seem to lock out others more often than other computers, but the problem is not limited to that computer exclusively. The problem occurs whether two computers are accessing the .mdb or 10 computers are accessing the .mdb.
