[mapserver-users] GDal Mini drivers and php script under IIS 7 on Windows Server 2008

Mon May 11 17:31:03 PDT 2015

The IIS logs show 403 error which is a forbidden resource

I would check that you have IIS set to serve CGI.

I would still be suspect of permissions as well. Create a new IIS
application / app pool for your script and set the app pool to authenticate
as a AD user and explicitly grant permissions on data and application
locations. You can roll this back later if it solves the problem.
