Open Workbench – Open Source Project Scheduling for Windows
http://www.openworkbench.org/

Open Workbench is an open source Windows-based desktop application that provides robust project scheduling and management functionality and is free to distribute throughout the enterprise. When users need to move beyond desktop scheduling to a workgroup, division or enterprise-wide solution, they can upgrade to CA’s Clarity™ system, a project and portfolio management system that offers bidirectional integration with Open Workbench.
