Scan to folder, destination folder not on C:\

I have a problem where I'm trying to set the scan to to be a separate drive than the c:\ drive, and a different location than \. It needs to go to something like D:\Shared\Scanned Docs. I can get it to work on a test folder using C:\Test, but cannot get it go to the D drive destiantion. Any tips on how I can accomplish that/if it's even possible? Thanks!
