(An internal error has occurred )远程桌面连接(Remote Desktop Connection)发生内部错误错误是一个非常模糊的错误消息。它主要发生在用户尝试连接到远程计算机时。这可能是由于网络连接较弱、远程连接配置无效等原因造成的。
RDP错误 – 发生内部错误
已知有助于解决Windows 11/10RDC错误的一些有效解决方案如下：
- 配置设置。
- 关闭所有 VPN 连接。
- 离开并重新加入域。
- 使用(Use)本地安全策略(Local Security Policy)实用程序。
- 更改 MTU 值
- 禁用网络级身份验证(Network Level Authentication)
您将需要一个管理员帐户来执行这些建议。
1]配置设置
通过在Windows 搜索(Windows Search)框中搜索来打开远程桌面连接客户端。(Remote Desktop Connection)
从屏幕的左下方选择“ 显示选项” 按钮。(Show Options )导航(Navigate)到 体验(Experience )选项卡。
如果连接断开，请取消选中(Uncheck)“ 重新连接”选项。(Reconnect if the connection is dropped.)
2]关闭任何VPN连接
打开 Windows 10设置(Settings)应用程序。导航(Navigate)到以下路径：Network & Internet > VPN.
选择您的计算机连接到 的VPN网络，然后选择(VPN)断开连接。(Disconnect.)
如果您使用任何第三方VPN软件，请退出该应用程序。
3]离开并重新加入域
要从域中删除系统，请使用以下过程：
- 单击(Click)开始按钮并打开设置(Start)应用(Settings)程序。
- 转到System > Accounts > Access work or school.
- 选择要断开计算机连接的组织。
- 选择断开(Disconnect)以断开与组织的连接。
- 重新启动系统。
这将断开系统与域的连接。
4]使用(Use)本地安全策略(Local Security Policy)实用程序
搜索 本地安全策略 (Local Security Policy )并选择适当的结果。在左侧导航面板中选择 Local Policies > Security options
在右侧面板上，双击系统加密：使用符合 FIPS 的算法进行加密、散列和签名。(System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing.)
它将打开配置对话框。
选择 启用。(Enabled. )选择 应用 (Apply )，然后选择 确定。(OK.)
重新启动(Reboot)计算机并检查是否可以解决您的问题。
5]更改MTU值
MTU或最大传输单元测量网络设备将接受的最大数据包。如果数据大小增加，它将减少任何连接断开的机会。虽然Windows不提供直接方法，但您可以使用此处提供的(available here)TCP优化器工具 ，然后更改 MTU 值。
选择自定义模式以启用MTU框，然后增加大小。您可能需要进行一些试验才能获得正确的值来解决错误。
6 ]禁用网络级身份验证(] Disable Network Level Authentication)
- 打开 Windows 设置 (Win + I)
- 导航到系统 > 远程桌面
- 取消勾选仅允许(Allow)来自运行具有网络级别身份验证的(Network Level Authentication)远程桌面(Remote Desktop)的计算机的连接复选框。
- 关闭设置窗口。
现在尝试连接到远程桌面，它应该有望解决问题。
MTU 越高越好还是越低越好？
如果MTUY太大，则可以承载更多数据，但数据可能会变得支离破碎。您需要尝试不同的值来确定路由器和计算机之间的工作原理。
为什么远程桌面(Remote Desktop)连接不起作用？
即使您的密码正确，也可能有多种原因。其中一些是网络问题、服务器端的身份验证问题、防火墙(Firewall)以及通过远程连接到计算机的选项。
远程桌面连接(Remote Desktop Connection)突然停止
如果您经常遇到这种情况，您可能希望减少与连接一起携带的连接设备的数量。它包括打印机、音频播放设置等。解决这个问题的最好方法是连接最低限度的设置，然后一次添加一个。
我希望这篇文章很容易理解，并且您能够找出远程桌面(Remote Desktop)出现内部错误的问题。
An internal error has occurred error for Remote Desktop Connection
An internal error has occurred error for Remote Desktop Connection is a very vague error message. It occurs mostly when a user is trying to connect to a remote computer. This could be caused by a weak network connection, an invalid configuration of the remote connection, and more.
RDP error – An internal error has occurred
Some of the working solutions that have been known to help resolve this RDC error in Windows 11/10 are as follows:
- Configure the settings.
- Turn off any VPN Connections.
- Leave and re-join a domain.
- Use the Local Security Policy utility.
- Change MTU Value
- Disable Network Level Authentication
You will need an administrator account to execute these suggestions.
1] Configure the settings
Open the Remote Desktop Connection client by searching for it in the Windows Search box.
Select the Show Options button from the bottom left portion of the screen. Navigate to the Experience tab.
Uncheck the option that says Reconnect if the connection is dropped.
2] Turn off any VPN Connections
Open Windows 10 Settings app. Navigate to the following path: Network & Internet > VPN.
Select the VPN network that your computer is connected to and select Disconnect.
If you are using any third-party VPN software, exit that application.
3] Leave and re-join a domain
To remove a system from the domain, use the following procedure:
- Click on the Start button and open the Settings app.
- Go to System > Accounts > Access work or school.
- Select the organization you want to disconnect your computer from.
- Select Disconnect in order to disconnect from the organization.
- Restart the system.
This would disconnect the system from the domain.
4] Use the Local Security Policy utility
Search for Local Security Policy and select the appropriate result. Select Local Policies > Security options in the left side navigation panel.
On the right-side panel, double click on System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing.
It will open the configuration dialog.
Select Enabled. Select Apply and then select OK.
Reboot your computer and check if that fixes your issues.
5] Change MTU Value
MTU or maximum transmission unit measures the largest data packet that a network device will accept. If the data size is increased, it will reduce the chance of any connection drop. While Windows doesn’t offer a direct method, you can use the TCP optimizer tool available here and then change the MTU value.
Choose the custom mode to enable the MTU box, and then increase the size. You may have to experiment a bit to get the right value to resolve the error.
6] Disable Network Level Authentication
- Open Windows Settings (Win + I)
- Navigate to System > Remote Desktop
- Un-tick the Allow connections only from computers running Remote Desktop with Network Level Authentication checkbox.
- Close the settings Windows.
Now try connecting to a remote desktop, and it should hopefully resolve the problem.
Is higher or lower MTU better?
While a larger MTUY can carry more data if it’s too large, the data can get fragmented. You will need to experiment with different values to determine what works between your router and the computer.
Why is the Remote Desktop connection not working?
There can be various reasons, even if your password is correct. Some of them are network issues, authentication issues on the server-side, Firewall, and the option to connect to a computer via remote.
Remote Desktop Connection stops all of a sudden
If you face this often, you may want to reduce the number of connected devices that carry along with the connection. it includes printers, audio playback settings, and so on. The best way to figure this out is to connect with the bare minimum setting and then add one at a time.
I hope the post was easy to follow, and you were able to figure out the problem where you get the internal error with Remote Desktop.
