I have been trying and trying to get Qgis Server to working on my Windows 7 machine with no luck. I have read every thread out there on the web related to how to install and nothing works. I'm beginning to think that it's all just a nasty joke that someone is trying to play and that there isn't really a Server available. If anyone has any step-by-step directions that actually work, would love to hear.
As per QGIS home page Qgis server actually exists. You can try the procedure mentioned by 'underdark' in the following link.
You may be aware 'underdark' is a moderator of gis.stockexchange.com So the procedure can't go wrong. All the best.
