Question: In Access 2003/XP/2000/97 how come when I can the configuration of a table that is linked, Access does not recognize these changes automatically?
Answer: In order for Access to recognize table changes to a linked table, you must refresh the link.
To do this, under the Tools menu, select "Database Utilities" and then "Linked Table Manager."

A Linked Table Manager window should appear as follows:

Select the tables that you wish to refresh the links for. In this example, we've selected the Employees table. Click on the OK button.

You should get a message indicating that the linked tables were successfully refreshed. Now, any changes to the linked table should be reflected in your database.
