There are four primary users for this database (Access 2003) - all with the same rights. Users 1 and 2 are, by far, the most frequent users. Here's the problem: User 2 cannot get into the database when User 1 is already on. User 2 gets bounced from the database if User 1 opens the database.Users 3 & 4 never have a problem whether User 1 or User 2 is in the .mdb or not.* The .mdb file is on a networked drive.* User 2 did not have problems with file access until he and User 1 got new computers and moved into new office space.* Compact & Repair appears to have had no effectIs this a problem with th associated .ldb file? Can / should the .ldb file just be deleted ?Thanks for any advice.
