linked server to specific access table
Setting up an Access DB as a linked server gets pretty ugly, but if you absolutely have to do it, you can split that one table into a separate database file, and create a linked table pointing to it from the original Access DB file. Then set up a linked server in SQL Server pointing to the Access database file with that one table.

Better option: Build an SSIS package that periodically imports/synchronizes data from your Access database.

Best option: Use the upsizing wizard in Access to migrate the data to SQL Server, and continue using Access as the front-end application, but not as the storage engine.
