Much thanks for your timely reply. I am a Microsoft Certified systems administrator with some clients that have issues with Microsoft or at least its leadership. They want no Microsoft products in their office. I would want a project server software that can be virtualized and support five simultaneous users. It should also have the ability to connect with Microsoft's project management client software such as 'Project Professional 2003" Much thanks for your continued guidance

I write to inquire if there is a 'Linux' Project management server or an open source equivalent to the Microsoft Server. New to Linux and would appreciate an informed opinion.
