Thread:Project:Support desk/Unable to upload new version of existing file/reply (3)

Thanks Zoglun, unfortunately we're on IIS. However, I figured out at what point the IUSR file permissions ceased to exist (right around the time we did the upgrade) and had to select the 15K files *before* that one, and then just add the IUSR permissions from there back. For some reason doing a directory level permissions and telling it to propagate to all the individual files wouldn't work. Either way, problem solved. :)
