Oh you’re in luck, with the original CD you can play the remake people have been working on! (requires some files from the original game but has been upgraded)
Dune Legacy - Dune Legacy is an effort by a handful of developers to revitalize the first-ever real-time strategy game. It tries to be as similar as possible to the original gameplay but to integrate user interface features most modern realtime-strategy games have like selecting multiple units.
Open source and cross platform
Modern display resolutions
Modern RTS controls like selecting multiple units and right-click commands
Original campaign with Harkonnen, Atreides and Ordos
Super Dune campaign with Fremen, Sardaukar and Mercenary
Multiplayer support
Map editor
