I have followed the IIS tutorial on setting up webdav, and have successfully connected a win8 client to it, both by mapping a drive in Explorer, and by using WebDrive. I can connect and read the remote folder contents, but I am unable to write anything to the folder. I have enabled NTFS permissions for all local users, and the webdav authoring rules are set to all file, all users, read, write, and source.
I am pulling my hair out over this, what am I missing?
