Connection reset by 10.251.130.26 port 22
查看Client的日志信息如下，没有明显的错误

打开server的日志开关
打开文件C:\ProgramData\ssh\ sshd_config，修改SyslogFacility的配置如下
# Logging
SyslogFacility LOCAL0
#LogLevel INFO
重启SSH server的服务
客户端再进行访问，在路径下发现有日志文件sshd
C:\ProgramData\ssh\logs
打开文件发现报如下错误：
8696 2021-04-21 12:03:03.033 fatal: check_group_membership CheckTokenMembership for user sshd failed with 1309 for group administrators
找了网上找不到可能的原因，打开sshd用户的信息，发现其是管理员，但是不属于Administrators组。
所以想到的解决方案是换个用户试试，lenovo修改下密码，密码不能为空，再尝试连接，发现没有问题了。
其实是没有彻底解决问题，就是变通了一下，具体解决可能要看看怎么设置sshd的用户信息。
C:\Users\lenovo>ssh -v lenovo @10.251.130.26
