我最近从 16.04 LTS 升级到了 20.04 LTS，现在我无法从 Windows/10 连接到 Ubuntu。
我确实有一个来自 Windows/10 的活动连接：
但是，我无法连接任何其他人：
C:\Users\rene>net use g: \\tristram\games
System error 53 has occurred.
The network path was not found.
C:\Users\rene>
smb.conf中的共享定义：
[Games]
comment = René's games on Tristram

writeable = yes
browseable = yes
follow symlinks = yes
veto files = /.*/*~/*.desktop/
create mask = 0740
directory mask = 0740
guest ok = no
valid users = rene
使用 smbclient 查看服务器，我得到以下信息：
rene@TRISTRAM:~$ sudo smbclient -L tristram -d 4

而从服务器到客户端没有问题：
