Re: [mapserver-users] Mapserver WMS under IIS 7 x64 serving up blank images
I figured out what was going on. It was an easting-northing mixup in the map and layer extents. Apparently earlier versions of mapserver/mapscript tolerated the bug. Anyway it's all working now under Windows Server 2008 x64 and IIS 7 FastCGI. A big thanks to the mapserver community. Open source rocks!
