From MarC Software:
CompareAll is a Windows tool for the side-by-side comparison of files/folders, COM+, IIS and users or groups. Compare directories and files (binary and text) using CRC-32; COM+ services (applications, components and properties); IIS services (applications and properties); users and groups, including properties. Green indicates the items are the same. Red means the items are different and blue shows that the item exists only in one place. Include or Exclude files, applications, components, and properties depending on the comparison. Save between sessions. View services or properties on one machine by entering the name in the left side only. Folders/files may be copied, moved, or deleted.
