This document takes Windows Server 2012 R2 operating system as an example to demonstrate the troubleshooting methods and solutions for failed or ineffective password resets on Windows Tencent Cloud Lighthouse instances.
Symptom
After the instance password reset, you receive the message **Due to system congestion, your instance password reset failed (7617d94c)**.
After the instance password reset, the new password does not take effect, and the login password is still the original one.
Possible Causes
The possible causes for failure or ineffectiveness of instance password reset are as follows:
The cloudbase-init component in Tencent Cloud Lighthouse is damaged, modified, disabled, or not started.
If third-party security software such as 360 Total Security or Huorong Security is installed on Tencent Cloud Lighthouse, the cloudbase-init component for password reset may be blocked, resulting in instance password reset failures.
If Tencent Cloud Lighthouse has been invaded and encrypted causing the password to be invalid, it is recommended that you back up the data and reinstall the system.
Directions
Based on the possible reasons for the unsuccessful password reset, two verification methods are provided:
