Hi Sanaa Al-Tamimi,
Thank you for posting in the Microsoft Community Forums.
Check the password policy:
Log on to an Active Directory management tool (such as Active Directory Users and Computers).
Check the user's password policy settings to ensure that they meet the organization's policy requirements.
If necessary, you can modify the password policy to shorten the password expiration time or force users to change their passwords.
Clear cached credentials:
On Windows clients, users can attempt to clear cached credentials. This can be done through the Credential Manager in the Control Panel.
Alternatively, try restarting the computer to clear any possible cached credentials.
Update credentials for applications and services:
Check and update all applications and services that use AD credentials.
Ensure that these applications and services use the latest AD credentials for authentication.
Check synchronization of local accounts with AD accounts:
Ensure that no local accounts are in conflict with AD accounts.
If there is a conflict, consider renaming the local account or disabling it to avoid confusion.
Event logging and auditing:
Check the Windows event log for details about logon attempts and authentication failures.
Configure Active Directory auditing to track events such as password changes and login attempts.
Best regards
Neuvi Jiang
