[What and Why:]<\/b><\/p>\n

Microsoft Defender for Identity is introducing a new sensor health issue, No Windows events received from domain controller<\/b>, to help administrators identify when Defender for Identity sensors are not receiving expected Windows events from a domain controller.<\/p>\n

This new health issue provides better visibility into potential event collection gaps that may affect Microsoft Defender for Identity detections, monitoring, and overall visibility for the affected domain controller.<\/p>\n

[Rollout Schedule:]<\/b><\/p>\n

    <\/p>\n
  • Available now.<\/li>\n

    <\/ul>\n

    [Impact on Your Organization:]<\/b><\/p>\n

    Who is affected:<\/b> <\/p>\n

      \n
    • Organizations using Microsoft Defender for Identity.<\/li>\n<\/ul>\n

      Service:<\/b> <\/p>\n

        \n
      • Microsoft Defender for Identity<\/li>\n<\/ul>\n

        After this rollout:<\/p>\n

          <\/p>\n
        • Administrators may see a new health issue, No Windows events received from domain controller<\/b>, in the Sensors health issues<\/b> tab and the global Health issues<\/b> experience.<\/li>\n

          <\/p>\n

        • The health issue will be displayed when Defender for Identity is not receiving expected Windows events from a domain controller.<\/li>\n

          <\/p>\n

        • The notification helps administrators identify and investigate potential event collection gaps that could affect Defender for Identity visibility and detections for the affected domain controller.<\/li>\n

          <\/ul>\n

          [Action Required \/ Recommendations:]<\/b><\/p>\n

          No action is required before the rollout.<\/p>\n

          If this health issue appears in your environment after rollout, review the affected domain controller and event collection configuration. If additional assistance is needed, contact Microsoft Support.<\/p>\n

          You may want to inform your security administrators about this new health monitoring capability.<\/p>\n<\/td>\n<\/tr>\n
