Why does not let samba into the ball?

Question

linux

Debian 7.
Installed samba4. Installed gadmin-samba. Configured (perhaps incorrectly?).
In windows, when you double-click on this server, it won't let you. windows cannot access.
Any ideas, comments on configuring gadmin-samba?
On the network, this folder should be accessible from domain computers and simple computers (just plugged into the network without settings / any settings for the name, group). In this case, it does not let from a computer under Windows 7, the computer is not in the domain, the workgroup is a workgroup. All addresses on the network are dynamic (except for servers), starting with 10 (10.0.11.12, etc.)
I'm trying to get into the Share folder (/root/Share/).
I want to make this folder publicly available for reading, writing and deleting files (file dump).

Answer 1

man smb.conf for the security parameter. And in general, it will not be superfluous to read it up and down, how samba is driven into a domain, what are its pros and cons.
Using GUI configurators for things as complex and frequently changing as samba can result in missing a required parameter. Configs need to be edited in the console.
