[mapserver-users] Mapserver WMS under IIS 7 x64 serving up blank images

[Tamas Szekeres]

Daniel,

This may also be an issue if GDAL couldn't actually open this file bacause
of any reason (permission?).
Make sure about this, by using a file monitoring tool, like SysInternals
filemon for instance.

Best regards,

Tamas
