To find out who might have a drawing open you can use the WHOHAS command.Keeping tighter control on drawings may require the use of AutoDesk Vault or some such similar program.John Connor2011-08-28 13:10:40

Unknown user?  Does it give you the remainder of the information as well?WHOHAS "After you select a file, the ownership information is displayed on the command
line. The information includes the current user's computer name, login ID, and
full name (if available) and the date and time the drawing file was opened."
