I have done that for every folder. It now lets them Upload new file but then gives the error: You do not have sufficient permissions to write to folder

I have checked, the ASP.Net account has full control and the AD user group has modify, read, write on the folder and it's subfolders. To recap: I have set the permissions to View, Add, Copy and delete on the folders in Admin-> File Manager Have set the File permissions on the folders to everything but full control for the ASp.Net account, the AD user group. the IUSR and network service accounts. Web Authors get the option to "upload new" but when they "upload selected" they get the error You do not have sufficient Permission to write to folder X. HELP!
