If you are using Access 2000, suggest that you familiarise yourself with the UpSizing Wazard. You'll get to this via the Tools, Database Utilities, Upsizing Wizard menu options.
This is a good starting point.
Another tool available form SQL Server install, and I think MSOffice Professional, is the "Import Export Data" tool, which allows you to transfer data between platforms.
Hope this helps,
