尝试将此计算机配置为^{(An error occurred while trying to configure this machine as a Domain Controller)}域控制器时出现错误消息最有可能在尝试将您的计算机提升为域控制器时发生。在这篇文章中，我们将为这个问题提供最合适的解决方案。

尝试将此机器配置为域控制器时发生错误^{(Domain Controller)}

如果您遇到此问题，您可以尝试以下我们推荐的任一解决方案来解决此问题。

1. 重新启动服务器计算机
2. ^(Use)在现有域控制器上^{(Domain Controller)}使用dsa.msc 管理单元

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

1]重新启动服务器计算机

尝试将此机器配置为域控制器问题时发生此错误 ^{(An error occurred while trying to configure this machine as a Domain Controller )}的最快解决方案是，像客户端机器一样执行服务器机器的完全重新启动。

服务器完成启动后，您可以尝试 DC 升级。如果错误仍然存​​在，那么您可以尝试下一个解决方案。

2]删除^(Delete)失败的服务器机器帐户

请执行下列操作：

• 启动Active Directory 用户^{(Active Directory Users)}和计算机^(Computers)(dsa.msc) 管理单元。
• 单击左侧窗格中的计算机^(Computers)。
• 在右窗格中，右键单击您作为成员服务器加入的故障服务器，然后从上下文菜单中选择删除。^(Delete)这应该会聚合 AD 复制。
• 接下来，在升级为域控制器^{(Domain Controller)}sysdm.cpl失败的服务器上运行命令，并强制将其从域中删除。
• 接下来，删除 AD DS 角色。
• 重新启动^(Reboot)服务器并重新安装AD DS服务器角色。

现在，您可以再次尝试使用Â 格式的升级凭据将机器升级为域控制器。^{(Domain Controller)}domain\user

补充笔记^{(Additional notes)}

下表（来自Microsoft）显示了所有内置日志（默认启用并配置为最大详细程度），这是解决域控制器升级和降级问题的最重要工具。

要解决日志未解释的问题，请使用以下工具作为起点：

• dcdiag.exe
• Repadmin.exe
• 自动运行程序^{(AutoRuns.exe)}
• 任务管理器
• MSInfo32.exe
• Network ^(t)Monitor 3.4（或任何第三方网络捕获和分析工具^{(network capture and analysis tool)}）

An error occurred while trying to configure this machine as a DC

The error message An error occurred while trying to configure this machine as a Domain Controller is most likely to occur when trying to promote your machine as a domain controller. In this post, we will offer the most suitable solution to this issue.

An error occurred while trying to configure this machine as a Domain Controller

If you’re faced with this issue, you can try either of our recommended solutions below to resolve the issue.

1. Restart Server computer
2. Use dsa.msc snap-in on the existing Domain Controller

Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Restart Server computer

The quickest resolution to this An error occurred while trying to configure this machine as a Domain Controller issue is, to perform a full restart of the server machine just like client machines.

Once the server completes boot, you can try the DC promotion. If the error persists, then you can try the next solution.

2] Delete the failed server machine account

Do the following:

• Launch Active Directory Users and Computers (dsa.msc) snap-in.
• Click Computers from the left pane.
• In the right pane, right-click the failed server you joined as a member server, and select Delete from the context menu. This should converge AD replication.
• Next, run sysdm.cpl command on the server that failed to promote as Domain Controller, and remove it from the domain forcibly.
• Next, remove the AD DS role.
• Reboot server and install AD DS server role back.

Now, you can retry to promote the machine as Domain Controller using the promotion credentials in domain\user format this time.

Additional notes

The table below (sourced from Microsoft) shows all the built-in logs (enabled and configured for maximum verbosity by default) which are the most important instrument for troubleshooting issues with domain controller promotion and demotion.

To troubleshoot issues not explained by the logs, use the following tools as a starting point:

• Dcdiag.exe
• Repadmin.exe
• AutoRuns.exe
• Task Manager
• MSInfo32.exe
• Network Monitor 3.4 (or any third-party network capture and analysis tool)

Hope you find this post helpful!
