Sometimes, when you want to modify your database, and you try to open it exclusively, an error message pops up reading “You cannot get into Exclusive Mode right now because this database is opened by other users or because you do not have permissions to open exclusively.” With AccUserList you can check who is connected, and tell him/her to disconnect.
 
With AccUserList you can easily get the list of users that have the mdb, mde, accde or accdb database file open.
 
You get the following information:
* Name of the workstation of the user (COMPUTER)
* Whether the user is currently connected to the database (CONNECTED)
* Whether the user was disconnected abnormally (SUSPECT_STATE)
 
All databases using the JET 4.0 engine are supported: MS Access 2000, 2002, 2003 and 2007
