Once the Mac has been recognised in the Windows environment you should be able to see the database on both platforms. This is taking into account that the Mac has M/S Access installed. In the Apple Menu select chooser and then click on the Appleshare icon, then click on Server IP address and enter the IP address of the server. The next window will give you a choice, select the Macshare. You should now be able to navigate to the shared folder whether you have it saved in the My document or on the Desktop etc.
