ClinicRecords uses microsft access database. This databse is in 2003 format i.e. .mdb file and security is my .mdw file.
Name of database file is clinicrecords.mdb and security file name is clincrecordssecurity.mdw. Both these files are to be kept in single folder of your server. From clinicrecords.exe file from each client machine from setting menu you have map to clinicrecords.mdb.
Below attached video tutorial shows how to implement security. I think I have made the tutorial informative enough to carry out this task all by your self.
