我对上面的链接有一个后续问题。
我在 FreeBSD 上运行 Samba 3.0.23d 版本 7.1
我按照上述方法更改了策略，但仍然无法使用 Windows 7 或 Server 2008 连接到 Samba 服务器。我觉得这是识别网络上的新机器的问题。Windows 机器可以看到 Samba 服务器，但无法连接到它或查看任何文件。更改安全策略后，Samba 服务器要求输入网络 ID 和密码，但不允许机器连接，说它们是未知用户名或密码错误。
这是我当前的配置文件。任何地方都没有任何加密的迹象，我应该添加这一行吗？不确定这在其他地方会有什么作用。

有时，Samba 会有一些缺陷，具体取决于平台。它（Samba）并不总是设置为使用加密密码。如果您导航到 /etc/smb.conf，它应该会提到一个暗示加密密码的配置项。将设置更改为与当前设置相反的值，然后发出命令：
/etc/rc.d/samba restart <- 需要 root 权限。要么在前面加上 sudo，要么直接输入 su。
或者
/etc/rc.d/smbd restart <- 需要 root 权限。要么在前面加上 sudo，要么直接输入 su。
重新启动 Samba 所需的命令取决于版本。几年前我遇到过这个问题，它困扰了我很长时间。还有一个开源项目叫做网页管理这对于远程或通过 Web 浏览器本地管理 *nix 机器非常有用。如果您决定使用 Webmin，请确保机器得到良好的保护。
以下是我的网络（Windows、Mac OS X、Linux、BSD）中 smb.conf 的示例，它们都在互相通信。下面的文件是从 Mac 上获取的。

; ============================================================================
;
; For the format of this file and comprehensive descriptions of all the
; configuration option, please refer to the man page for smb.conf(5).

; The following configuration should suit most systems for basic usage and
; initial testing. It gives all clients access to their home directories and
; allows access to all printers specified in /etc/printcap.
; BEGIN required configuration
; Parameters inside the required configuration block should not be altered.

我了解到 SAMBA 有时会时好时坏。我已在 ubuntu 服务器上配置了它，但我发现通过 Windows 7 机器连接到它总是很困难。
您可以首先查看 Samba 的日志文件，看看当您尝试从 Windows 机器输入用户名/密码时究竟发生了什么。
答案3
根据 Windows 连接的 SMB 协议版本，您可能希望client use spnego = no在 smb.conf 中切换选项（如果没有则添加它）。
