我的服务器是运行 CentOS 7 的机器samba-4.10.4-11.el7_8.x86_64
服务器正在侦听 IPv4 和 IPv6
tcp6 0 0 :::445 :::* LISTEN 1332/smbd
tcp6 0 0 :::139 :::* LISTEN
我有一台 Windows XP 虚拟机和一台 Windows 10 笔记本电脑。我在XP机器上进行测试，但在Win10上得到同样的错误。
我可以通过 IPv4 查看服务器：
C:\Documents and Settings\sweh>net view \\mercury7.spuddy.org
Shared resources at \\mercury7.spuddy.org
Mercury7
Share name Type Used as Comment
-------------------------------------------------------------------------------
gluster-gluster Disk For samba share of volume gluster
phone_media Disk Media to sync from phone
profiles Disk
scans Disk Scans from printer
sweh Disk
The command completed successfully.
但是，如果我尝试通过 IPv6 执行相同操作，则会收到错误 53：
C:\Documents and Settings\sweh>net view \\mercury7-g.spuddy.org
System error 53 has occurred.
The network path was not found.
（“-g”地址只有 AAAA 记录才能强制使用 IPv6）。
tcpdump port 445在服务器上执行 a显示 IPv6 上根本没有收到任何流量，但 IPv4 上有大量流量
我知道 XP 机器可以通过 IPv6 查看服务器，因为它可以 ping
C:\Documents and Settings\sweh>ping mercury7-g.spuddy.org

也没有适当的防火墙或网络过滤器，因为 atelnet mercury7-g.spuddy.org 445建立了连接，我们可以在tcpdump输出中看到它。

所以似乎有什么东西坏了前网络层net view甚至阻止与网络通信。
我该从哪里开始寻找呢？
