NETLOGON not shared

Alerts Appendix > Domain controller alerts > NETLOGON not shared

NETLOGON not shared

Indicates that the NETLOGON folder is not shared. File Replication Service requires this folder to be shared on domain controllers for replication to work correctly.

Data collector
•
Category: Validations
•
Name: Is the domain controller folder Netlogon shared
•
Supported on: Windows Server 2016, Windows Server 2019, and Windows Server 2022
•
Required permissions: When monitored locally and remotely, only domain user privilege is required. When monitored remotely, the target server must have WMI remote access enabled and the user must be a member of the Distributed COM Users group.
Description

Logon scripts for a domain controller are found under the NETLOGON admin share for Windows NT. On Windows NT domain controllers, the %SystemRoot%\System32\Repl\Import\Scripts folder is shared as NETLOGON. Dcpromo modifies the registry value that defines the path to the NETLOGON share to %SystemRoot%\Sysvol\Sysvol\domain_name\Scripts.

The default folder structure is:

%SystemRoot%\Sysvol\Sysvol\domain_name\Policies
%SystemRoot%\Sysvol\Sysvol\domain_name\Scripts

Any changes to the %systemroot%\SYSVOL folder on any domain controller are replicated to the other domain controllers in the domain. Replication is RPC based.

You can use NETLOGON and SYSVOL to distinguish between a domain controller and a member server. If both the NETLOGON and SYSVOL shares exist on a server, it is a domain controller. When dcpromo demotes a domain controller to a member server, the NETLOGON share is removed, so the presence of only SYSVOL indicates a member server.

Resolution

All potential source domain controllers in the domain should themselves have shared the NETLOGON and SYSVOL shares and applied default domain and domain controllers policy.

SYSVOL directory structure:

Category: Windows Services
•
Name: Netlogon Windows Service
•
Supported on: Windows Server 2016, Windows Server 2019, and Windows Server 2022
•
Required permissions: When monitored locally, only domain user privilege is required. When monitored remotely, domain administrator privilege is required.

•
Supported on: Windows Server 2016, Windows Server 2019, and Windows Server 2022
•
Required permissions: When monitored locally or remotely, read access to SYSVOL.
Description

The Directory Analyzer agent compares the representation of GPOs stored in the local SYSVOL with GPOs found in Active Directory. This alert is active when a GPO represented in the local SYSVOL is not found in Active Directory.

Resolution

Review the reported orphaned GPO folders in the local SYSVOL and remove any that are obsolete.

Physical memory

Alerts Appendix > Domain controller alerts > Physical memory

Physical memory

Indicates that issues have been detected for the physical memory on the domain controller.

Data collector
•
Category: General
•
Name: Memory degrade
•
Supported on: Windows Server 2016, Windows Server 2019, and Windows Server 2022
•
Not supported on: Virtual computers
•
Required permissions: When monitored locally, only domain user privilege is required. When monitored remotely, the target server must have WMI remote access enabled and the user must be a member of the Distributed COM Users group.
Description

The Directory Analyzer agent monitors the Memory degrade data collector on the domain controller. When the physical memory of the selected domain controller has a status other than OK for a period of time equal to or longer than the configured threshold, this alert is raised.

Resolution

Review the device configuration and contact your hardware vendor if required.
