No matter what I do I can't add a Net Folder Server to my appliance. I'm trying to get at the "Data$" share on my primary file & print server. I using domain admin credentials

CN=Administrator,CN=Users,DC=domain,DC=com

I've tried all variations of Server path, and Proxy name and I either get "Authentication error" (when using \\ip-addr\share) or "A network error occurred testing the connection" (when using \\servername\share)

Help!
