If your goal is to periodically import data from Access to SQL Server you can set up and schedule a Data Transformation Services (DTS) package to do the extraction. If you have queries that rely on data from SQL Server and Access, you can set up the Access database as a linked server.
Both searchDatabase.com and SQL Server Magazine have good articles and tips on DTS. Search the SQL Server Books On Line index for "linked servers" for more information on configuring and using a linked server.
