1. Problem description
When using Remote Desktop to connect to an ECS instance on a Windows system, an error message " For security reasons, this user account has been locked due to too many login attempts or password change attempts " is prompted. The specific error message is as shown in the figure below.
2. Cause of the problem
The user lock policy is configured in the ECS instance system group policy of the Windows system. If you enter an incorrect password too many times when logging in, the account will be locked, making it impossible to log in to the remote desktop.
3. Solution
You can modify the Windows instance Group Policy account lockout threshold to 0 to solve this problem. This article uses the Windows Server 2019 operating system as an example. The steps for other operating systems are similar.
- Connect to Windows instance via VNC.
When you cannot use Workbench and third-party remote connection tools (such as PuTTY, Xshell, SecureCRT, etc.) to connect to the instance, you can log in to the instance through VNC remote connection.
For specific methods, different service providers provide different consoles, so please check it yourself.
