Today I did a web site update and got this strange behavior I never experienced before. I always copy files from a build folder to the prod folder. After I copied the file, I started getting a permission denied error in the web site, so I went to the file's property and noticed that it didn't has any of the corresponding permissions. My thought is that when copied the file, it didn't get the permissions inherited. Do you think this is something possible, and if so, what did I do wrong that caused that behavior?
