I've written a very useful and productive program for the medical facility I work in. The problem is as follows: the program opens an Access 97 database that is stored on a network drive...the program itself is installed on four different computers which are linked to the network drive that contains the database...the database is password protected, this is taken care of at the logon screen...the problem arises when someone from computer #2 i.e., wants to use the program when someone on computer #1 is already using the database...the database is supposed to be shared, but only one person can use it at a time...I've tried the database properties in Access and it is supposed to be "shared" not exclusive...any help ???
