there's lots of Open Source CMS out there, mostly based on the LAMP (Linux, Apache, MySQL, PHP) architecture, but a few for Windows and even for Macintosh. Among the most commonly used, with numerous of installations (and therefore a quite active userbase) are:
Typo3: steep learning curve, but after that the sky is the limit
Mambo/Joomla!: much much easier to learn, but somehow limiting in the long run and quite controversially discussed due to inherent security issue
Wordpress: primarily a blog solution, but thanks to a very flexible template system often used as a non-blog-CMS too, very easy to use
I would recommend to look at one of these three, but as has been said before, there's zillions of others.
