Does anybody know what ports are used when I run net use * \servernameshare PWD /User:USER ? The firewall is stopping it somewhere although ports 137, 139, 445, and 8471-8477 are open on the firewall. It eventually times out with "System error 53 has occurred - The Network Path was not Found" With all ports open it works immediately and maps the drive - but this is not practical when in production.
