1. Reset the Password  

   - Change the user’s password in Active Directory and try logging in again.  

2. Verify Username Format

   - Check that the **User logon name** and **User logon name (pre-Windows 2000)** fields match correctly.  

3. Check Account Status  

   - Confirm the account is not disabled.  

   - Verify the user is not locked out.  

4. Domain Controller Availability  

   - Make sure the Cloud Computer/VM can reach the DC.    

5. Time Synchronization  

   - If the VM’s clock is more than 5 minutes out of sync with the DC, authentication will fail.
