The most frequent cause is a policy within the Local Group Policy or Active Directory, often related to password complexity requirements or time-of-day restrictions. Additional factors like account lockouts or restrictive group policies may also contribute to this issue, necessitating a review of security settings and policy configurations. Now that you are aware of the potential causes of the error message, you can isolate your issue by using the solutions provided below.
1. Disable Windows Group Policy
When strict Group Policy settings prevent logins, temporarily disabling them can help find the problem. Turning off these policies removes restrictions like password requirements or login times, making it easier to access accounts and spot issues.
2. Set up a Password
Having a blank password often causes this error since many security policies block accounts without a password from signing in. Setting a password for your account meets these security standards, enabling the system to process your login successfully.
