If you put the server behind a firewall, then you can not only block access by IP address, but by almost any other type of restriction you wanted to implement.
Best bet is to set security properties on the data you want to protect. If you set NTFS permissions and either allow a certain group or deny a group of users access you will control access to those files files.

If you live outside the United States, by submitting your email address you consent to having your personal data transferred to and processed in the United States.
You could also use the host based firewall on the server itself.
Thanks for all the suggestions!
