I am trying to publish WEBDAV directories for students on my webserver. When I create the directories on the webserver, I can publish them just fine. But when I change that virtual directory in IIS to a share on another server, it will not authenticate properly. I don't think it's a problem with the ISA server, but it's possible. I've tried all sorts of combinations, but it doesn't look like it's passing the credentials properly when the folders on are a network share instead of a local directory. I'm thinking my other option is to put IIS on that other server, then publish that through the ISA server, with a redirect on the original webserver. Anyone have any experience with this on WEBDAV?
