更新：此问题仅出现在 上Windows server 2008 R2。我创建了一个Windows server 2012 R2虚拟机，它运行良好。
我想通过 ssh 运行一些 Windows 查询，但这是一个有趣的问题，我无法找到其原因。
使用密钥进行身份验证时出现以下错误：
root@ubunutu: ssh -t [email protected] "schtasks /query"
ERROR: A specified logon session does not exist. It may already have been terminated.
GPO“不允许存储网络身份验证的密码和凭据”已被禁用。
如果我使用密码验证并返回查询的输出，它就可以正常工作。
-D如果我使用或启动远程 cygwin 服务器上的 sshd，-d然后使用密钥或密码进行身份验证，它也会起作用。
更新：只要服务由我们验证的同一用户启动，它就可以工作。username@cygserver: /usr/sbin/sshd.exe
默认情况下cygrunsrv --start sshd以 SERVER_NAME/cyg_server 用户启动。
username@cygserver: /usr/sbin/sshd.exe -D
or
username@cygserver: /usr/sbin/sshd.exe
root@ubunutu: ssh -t [email protected] "schtasks /query"
...output of all schedule tasks
其他 Windows 命令运行良好。
