Description

The "Active Directory" Service Template ads the "Active Directory 2012 - DRA" service. However, this service will show as misconfigured in some cases.

Environment

  • N-able N-central
  • Windows Server 2012 or 2012 R2
  • Active Directory Domain Controller role enabled

Solution

  • There are 2 Active Directory classes in WMI (NTDS_NTDS or DirectoryServices_DirectoryServices). Which class is present depends on the Domain Functional Level.
  • The "Active Directory 2012 - DRA" service monitors only the NTDS_NTDS class, and does not allow to be reconfigured to monitor the other class.
  • If Win32_PerfFormattedData_NTDS_NTDS class does not work on Active Directory, the command returns:
Wmic path Win32_PerfFormattedData_NTDS_NTDSNode - LAB-TEX-DNS-02ERROR:Description = Invalid class
  • Check NTDS performance registry :
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NTDS\Performance
  • If the Classes exist then try running the following command to verify if the data is missing.
C:\Windows\system32>WMIC PATH Win32_PerfRawData_DirectoryServices_DirectoryService GET /VALUE
C:\Windows\system32>WMIC PATH Win32_PerfRawData_NTDS_NTDS GET /VALUE
