The availability of Active Directory Domain Service (AD DS) depends on the specific environment and configuration. If AD DS is not available, it could be due to various reasons such as network connectivity issues, server downtime, or configuration errors. It is important to troubleshoot the specific issue and address any underlying problems to ensure the availability of AD DS for the organization's users and systems. Regular monitoring and maintenance of AD DS can help prevent and resolve availability issues. **

To output users filtered in Active Directory, you can use PowerShell commands to query and filter the users based on specific criteria such as department, title, or any other attribute. You can use the `Get-ADUser` cmdlet with filters like `-Filter` or `-LDAPFilter` to retrieve the desired user information. Additionally, you can combine filters using logical operators like `-and` or `-or` to further refine your search results. Finally, you can output the filtered users to a CSV file or display them directly in the PowerShell console for further analysis or processing. **

Active Directory does not work on the Synology DiskStation because the DiskStation runs on a Linux-based operating system, while Active Directory is a Microsoft technology designed to run on Windows Server. Active Directory requires specific Windows Server features and functionalities that are not present in the Linux environment of the DiskStation. As a result, the two systems are not compatible for running Active Directory services. **

To assign group permissions in Active Directory, you first need to create a security group in Active Directory Users and Computers. Then, you can assign the appropriate permissions to that security group by right-clicking on the object or resource you want to assign permissions to, selecting "Properties," navigating to the "Security" tab, and adding the security group with the desired permissions. This way, you can easily manage permissions for multiple users by simply adding or removing them from the security group. **

To filter and display users in Active Directory, you can use the Active Directory Users and Computers tool. First, open the tool and navigate to the desired organizational unit (OU) or container where the users are located. Then, you can apply filters by right-clicking on the OU or container, selecting "Find," and specifying the criteria you want to filter by, such as user attributes or group membership. Once you have applied the filter, the tool will display only the users that meet the specified criteria. **

To move an Active Directory Organizational Unit (OU) to another one, you can use the Active Directory Users and Computers (ADUC) console. Simply open ADUC, locate the OU you want to move, right-click on it, and select "Move." Then, choose the destination OU where you want to move the selected OU. Confirm the move, and the OU will be transferred to the new location. Make sure you have the necessary permissions to move OUs within Active Directory. **

The Active Directory Domain Service can be enabled or installed on a Windows Server by using the Server Manager. In the Server Manager, navigate to the "Add roles and features" option and select "Active Directory Domain Services" from the list of available roles. Follow the installation wizard to complete the installation process, which includes configuring the domain and promoting the server to a domain controller. Additionally, the Active Directory Domain Service can also be installed using PowerShell by running the Install-WindowsFeature cmdlet with the appropriate parameters. **

The Active Directory Domain Service can be activated or installed by first installing the Active Directory Domain Services role on a Windows Server. This can be done through the Server Manager by selecting the 'Add roles and features' option. Once the role is installed, the Active Directory Domain Service can be configured by running the Active Directory Domain Services Configuration Wizard. This wizard will guide you through the process of setting up the domain, creating users, and managing permissions within the Active Directory. **
