Remote desktop connection was dropped due to data encryption bug --- and local connection fix bug

The remote desktop connection was disconnected due to a data encryption error:

go to the Registry Editor window, expand
"HKEY_LOCAL_MA CHINE\SYSTEM\CurrentControlSet\Services\TermService\ Parameters",
find the subkey named "Certificate" and delete it , restart the XP system or Windows 2000 Server server, the
system will regenerate the "Certificate" subkey, so that the client can connect to the terminal server normally.
This is because the Certificate subkey is responsible for the authentication and encryption of data messages in Terminal Services communications. Once it is corrupted, the Terminal Services protocol component will detect an error and interrupt the communication between the client and the Terminal Server. There are many reasons for the damage of the Certificate subkey, such as the administrator installing and uninstalling some system software, unreasonable configuration of terminal service parameters, etc. At this time, we need to reset the content of the key value to repair the terminal service.
　　After the terminal server cannot be connected, we must first determine whether it is caused by a network failure, and detect the remote client and XP system (Windows 2000 Server). Server) can be connected to the network normally; then it is necessary to check whether the encryption level of the terminal server is set too high. After eliminating the above reasons, it is possible that the "Certificate" subkey is damaged. In addition,
corrupted "X509 Certificate" and "X509 Certificate ID" under "HKEY_LOCAL _MACHINE\SYSTEM\Cur rentControlSet\Services\Term Service\Parameters" may also cause problems with Terminal Services, their fixes are the same as the "Certificate" subkey The repair method after damage is the same.
