无法访问samba服务器

我无法连接到运行CentOS 6.4（最低安装）的samba服务器，该服务器不在我的networking中。

当我尝试与Windows 7客户端连接时，连接失败，并显示默认的“无法访问”对话框。

我到目前为止所尝试的是：

• 打开我的samba服务器上的端口137,138,139,445
• 通过使用nmapvalidation端口是打开的（在samba服务器上）
• 尝试从我的客户端上面提到的端口远程login，但连接也失败了
• 重新安装桑巴并重新configuration服务
• closuresSELinux临时

iptables的

• CentOS 7，smb服务需要`systemctl restart smb`才能工作
• 任何方式来加快在Windows中映射的EFS共享？
• 桑巴 – 有没有办法让一个组只能查看\编辑\写下某个文件夹，在一个共享下？
• 虚拟化桌面
• 在networking共享上删除文件夹

Samba版本

 #smbd --version Version 3.6.9-168.el6_5 

工作组在smb.conf中正确设置，nmb正在运行。
