What do you mean by your active directory not working ?
- AD Services are Down: The Active Directory Domain Services (AD DS) might be unavailable, causing problems with authentication, user logins, or access to domain resources.
- Replication Issues: If there are problems with replication between domain controllers, users may experience inconsistent data, outdated group policies, or changes not being reflected across the network.
- DNS Issues: AD relies on DNS for locating services and domain controllers. DNS misconfigurations or failures can prevent clients from finding domain controllers, leading to login failures or other connectivity issues.
- Authentication Failures: Users might be unable to log in or access resources due to Kerberos or NTLM authentication issues, expired certificates, or network connectivity problems.
- Group Policy Failures: If Group Policies are not being applied correctly, users may face issues related to system settings or permissions.
- Access Control Problems: Permissions in AD may not work as expected, leading to unauthorized access or inability to access certain resources.
- Performance Issues: If AD is slow or experiencing high latency, it could impact how quickly users can log in or access shared resources.
- Schema or Configuration Problems: Misconfigured AD settings or schema modifications can disrupt operations or break specific AD functionalities.
