Found a nice (Freeware) tool called "Unlocker" for deleting/unlocking some stubborn files that a Windows 2008 machine just couldn't delete with its built-in tools.
It did the job without a hitch!
Scroll down about half way of the following page to get to the downloads section: http://www.emptyloop.com/unlocker/
This link goes directly to the portable package that contains both the x86 & the x64 versions of the tool
