Re: Trying to get tilecache/openlayers to work - IIS
Did you give full permission to your cache folder in Windows?
Try giving full permission to "everyone" on your folder and see it that works (i.e. C:\Inetpub\wwwroot\tilecache\Cache). Tilecache needs to have permission to save map tiles to this folder. I that works, then find a more appropriate permission setting.
