To add to Abhinav's answer, since this is an Access project, the client needs to have direct access
to the database files. This means that you most likely have to share the folder where the files are located.
For the future. If you plan to have more clients and you want to achieve more secure and robust environment, I'd suggest that you would have a look at SQL Server Express Edition: http://www.microsoft.com/sqlserver/en/us/editions/express.aspx
]. Migrating to SQL Server at this point could be well worth the time for the future.
