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

Mon May 11 11:01:35 PDT 2015

Still no resolution to this issue.  I gave the DefaultAppPool user Full Control over the MapData directory.  No help.  I then set Full Control of MapData to "Everyone".   Still no help.  I did figure out that Windows Server 2008 R2 doesn't come with the MS C++ Redistributables by default.  I installed those and now I can run the PHP script from the command line.  I still can't make URL request to the mapserver  requesting anything from the GDAL WW Minidriver though.  Below are the IIS log and Mapserver log entry.  Any additional suggestions on how to troubleshoot this would be greatly appreciated.

 Here are the logs from IIS:

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

Hi,

Definitely looks like a permissions issue.
Try granting read-access on the c:\MapData folder to "IIS AppPool\DefaultAppPool" user - assuming this is the application pool that MapServer and/or PHP is running under using CGI.
If that fails try granting "Everyone" read-only access to see if it is permissions.

Regards,

Seth

From the IIS log, it looks like the server is getting the request, php must be reading the script and calling the mini driver.  It looks like the gdal mini driver is trying to read the base imagery and is failing.  Here is a piece of the IIS log:

The pieces I have to work with are the map file, the layer XML files, for example Land-Sea.xml, the Tile.php script, (which seems to be working), and the tiled image set.  These same pieces work great with the same version of Mapserver, from GISInternals, on Windows 7 running IIS 7.  I'm thinking that this must be a permissions problem on Windows Server 2008.  Any ideas on where to go from here would be appreciated.
