If it is within a network, share the folder that the database file is in, and set apt permissions. For more information, see the article How do I use an Access database from multiple computers (in a network)? from our Database Development FAQs/Tutorials (at the top of this forum)

If it is over the internet, it would be far easier and much more reliable to change from Access to a server-based database system.
