You need to be using SQL Express on the main server machine.
Then with ports etc setup for sharing database you set the database connection string to point to the server rather than locally on the second machine.

See kendash’s thourough tutorial here;

Depending on what DB type your already using you might not need the conversion bit but rest is all there.
