I am trying to deconstruct a database that has several linked tables. Is there a way to find the source database for the linked table from within the original database?
Tools>Database Utilities>Linked table Manager.
this list all of the linked tables so you should be able to see the paths there, unless the paths too long
You can also view the system objects, i.e. Tools->Options->View, and then click System Objects. Then open the table MSysObjects. The Database column will show you where the tables are linked from.
