Looking for duplicate file finder solution

I'm looking for a software that can find duplicate files of all types either locally or remotely (network share). The app should be able to find files not just by name but by "signature" (something like MD5 hash). It should be able to find duplicates even if the filenames do not match but contents are the same (that's where other, more "intelligent" comparison mechanisms come into play).

Please don't post top 5 google searches - I can use google myself quite nicely. This will need to run on XP/2K3, free solution would be ideal, any solution that is licensed should be reasonably priced and if it is commercial solution, it has to be by an established compan, not by fly-by-night company that won't be there tomorrow to support the product.

Thanks in advance!

I use this freeware application and it does just about everything you want *including* search by signature using either SHA or MD5 hashing algorithms.

Duplicate Files Searcher is an application for searching and deleting duplicate files on your computer. It is a platform-independent application.

Thanks for the link. Looks like an interesting utility but it appears a bit sluggish, possibly due to it being java-dependent and since it requires java we may not be able to use it, as not every system has java installed. Let's see what else surfaces...

I just ran duplicatefilesearcher - ran for over an hour just trying to get a listing of folders on a 40GB volume. I'm afraid that won't work. So, I guess it's back to the drawing board with an added requirement:

The solution must be robust.
I'll close this request out and re-open it, as I think it landed in a wrong area. I also want more eyes to look at it. Thanks souseran, sorry it didn't work out.

Before you close it, try this one:

Easy Duplicate Finder

http://www.easyduplicatefinder.com/

Faster than Duplicate Files Searcher. Not Java dependent, and does CRC32 Checksum +FileSize comparisons.

Oh, and it's freeware.

Thanks for your suggestion but it didn't work out - software crashed hard several times on different systems, esp. when it needs to enumerate large volumes. Can't use it. Thanks for your recommendation anyway.
