[gdal-dev] GDAL WorldWind Mini-Drive problem under Windows 2008 R2 on VM

[EVANS, JAMES R GS-13 USAF ACC 84 RADES/SCZE]

I did try gdal_translate and it does fail.  Here's what happens at the command prompt:

C:\MapData>gdal_translate -of JPEG -outsize 512 512 land-sea.xml test.jpg
Input file size is 20480, 10240
0ERROR 1: GDALWMS: Unable to download block 0, 0.
  URL: http://localhost/mapserver/content/tile.php?T=Land-Sea&L=0&X=0&Y=4
  HTTP status code: 200, error: (null).
ERROR 1: land-sea.xml, band 1: IReadBlock failed at X offset 0, Y offset 0

GDALINFO works just fine.  I did try running the command prompt as an administrator, with no luck.  I'm not sure how to solve this.  I would think it is a permissions problem, but maybe a missing environment variable or something?  At least I do have a working system at home to help troubleshoot this.  Any help would be appreciated.
Thanks,
James

Hi,
I was running Mapserver under Windows 7, using the gdal worldwind minidriver to serve up imagery from various tile sets.  I'm trying to migrate to Server 2008 R2.  I don't seem to be able to get the mini driver to work and it looks like a permissions issue.  Any suggestions on how to troubleshoot this would be greatly appreciated.  Here is a log entry from Mapserver showing the failure.  I have given "Everyone" and "DefaultAppPool" Full Control over the C:\Mapdata directory.  
Thanks,
James

Here's what happens in the Mapserver Log:
