itunes and airport extreme drive

Hi,

I THINK I did a comprehensive search for this topic, but didn't find anything. If this is already posted info, then I apologize in advance. I'm running the latest version of Parallels and Windows 7 on my macbook pro. My itunes media drive is an external plugged into my airport extreme. I'm not able to navigate to that drive to tell my windows version of itunes where it is located. This location works fine on all locally connected computers as they are able to access and play that media. I think I'm overlooking a simple solution, but have no idea where to find it. I tried changing my network connection from shared to bridged. No change there. Any other suggestions from folks that have had this problem? I'm running OSX 10.6.7. Thanks in advance for any direction.

David
