Unique Workstation ID Generator

I need a .DLL file that will generate a unique ID based on all the hardware installed in a computer. Rules: 1. The returned ID must be 255 characters or less 2. Running the routine will return the exact same value every execution unless the computer's hardware has changed. 3. The DLL must be able to be accessible by .NET Interop services 4. The DLL must function properly with an account that only has "User" privileges under NT 4.0, 2000, XP, 2003. I would prefer to have the DLL written in C/C++, but this is not a requirement. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
