Undeleting files

My server is running windows 2000 advanced server with terminal services. While creating client profiles, i directed some user profiles to be created in an existing folder with data. This must have overwritten the existing data which i cant find anymore. This data originally was sitting on a D drive( separate physical drive), and later cut and pasted over to C drice(another physical drive) where it has now been overwritten. Is there any way/software to recover this data?
