A screen cast of the process I am following can be viewed at: http://www.okacs.com/screencasts/Linked Server – Secured MS Access.swf

And this is the SQL that I am using to create the linked server:
– ========================================
– Add Linked Server Access MDB template
– ========================================
EXEC sp_addlinkedserver
@server = N’Database1′,
@provider = N’Microsoft.Jet.OLEDB.4.0′,
@srvproduct = N’OLE DB Provider for Jet’,
@datasrc = N’C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\Database1.mdb’
GO

– Set up login mapping using current user’s security context
EXEC sp_addlinkedsrvlogin
@rmtsrvname = N’Database1′,
@useself = N’FALSE’,
@locallogin = NULL,
@rmtuser = N’Admin’,
@rmtpassword = ‘secret’
GO

– List the tables on the linked server
EXEC sp_tables_ex N’Database1′
GO

– Select all the rows from the Customer table
SELECT * FROM Database1…Customers
