Solved: The Security Database on the Server Does Not Have a Computer Account for This Workstation Trust Relationship - Part2
条评论在 Part1 里面,我们用 ADSIEdit.msc 解决了用户登录域的问题,在 Part2,我们来看看可能的另外一个原因:
用户计算机录域的时候出现如下错误:
Error: The security database on the server does not have a computer account for this workstation trust relationship
退出域重新加域,问题解决,可是第二天早上又在出现。
检查 AD 的日志,发现有 Event 5722 NETLOGON 错误:
Event 5722: The session setup from the computer ComputerName failed to authenticate. The name(s) of the account(s) referenced in the security database is ComputerName$. The following error occurred:
Access is denied.
在用户端的电脑上,也有Event 3210 NETLOGON 报错:
Event 3210: This computer could not authenticate with \DC01.contoso.com, a Windows domain controller for domain Contoso, and therefore this computer might deny logon requests. This inability to authenticate might be caused by another computer on the same network using the same name or the password for this computer account is not recognized. If this message appears again, contact your system administrator.
注意红色加粗标注部分,实际上,计算机账户的密码,也就是所说的 Secure Channel 安全通道,这个密码是由客户端发起的,一般不存在无法识别的问题,所以很有可能是在网络中有同名的计算机存在。
后来经过排查,发现有两台计算机重名,两台在碰到无法登陆域的情况下都有做退域重新加域的动作,哪一台后加域,另外一台就会出现无法登陆域的情况,因为在加域的时候,会重置计算机账户密码,所以对于原来已经加域的计算机来讲,密码就不一致了,导致安全通道被破坏,无法认证,最终不能登录域。
解决方法:将重名的计算机退域,改名,再重新加域,保险起见,用 netdom 重置下计算机账户密码 (重建 Secure Channel)
