Mapping a drive from an Amazon EC2 Instance of Windows Server 2008

First i want to say in advance, "Thank You" to everyone for your input. My question is "How do I map a drive from an Amazon EC2 instance to my local machine?" I have tried doing this the standard way of entering the IP (public and private) into the server field. I really just want users to be able to use login credentials to access drives on the Amazon EC2 instance. Any help is so very appreciated.

Thank you again, Perris Davis

p.s. My local machine is running Windows 7 and the Amazon instance is Windows Server 2008. Thank you again.
