I would like to do a site-to-site NET USE. I can do it successfully on the LAN - net use x: \\xxx.xxx.xxx.xxx\sharename /user:username password
Now, I would like to do it from outside the LAN. When I try, I get either "System Error 5 has occurred. Access is denied." or "The path cannot be found." I did some research and believed I needed to open ports 137-139 and forward them to my machine with the shared resource. Also the IP above was the public IP of my router.
Alternatives might be WebDAV, VPN, remote desktop, etc. But I really would like to do it this way. Any ideas?
