EXPLANATION    This message should occur only on a down-level computer. Any action to correct the problem should be performed on that computer.  The user accounts database, NET.ACC, is missing, damaged, or in a format that is incompatible with this version of LAN Manager.    ACTION    Copy the backup file, NETACC.BKP, to NET.ACC. If NETACC.BKP does not exist, copy NET.ACC or NETACC.BKP from a backup floppy or from the LAN Manager distribution disks.    If you have upgraded your LAN Manager software, you may need  to convert the user accounts database to a new format. See the instructions that came with your upgrade.
