Description: Microsoft LAN Manager Alerts MIB version II providing SNMP trap definitions for Windows network services and LAN Manager events.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is LanMgr-Alerts-II-MIB?

LanMgr-Alerts-II-MIB is a Microsoft proprietary module (version II of the LAN Manager Alerts MIB) that defines SNMP trap/notification objects corresponding to classic Windows LAN Manager service alerts. It focuses on event and fault notification rather than polled data tables, covering conditions such as service errors, print alerts, and user/administrative alert categories inherited from the original LAN Manager alerter service. Its monitoring role is almost entirely software/service status: it lets an SNMP manager receive traps reflecting Windows service faults, printer problems, or administrative alert conditions on a monitored host. It is tied to the legacy Microsoft LAN Manager/Windows networking alert framework and is generally used alongside the standard Windows/host MIBs (such as HOST-RESOURCES-MIB) for fuller system visibility. It would typically be found in older Windows NT-era enterprise network management deployments that still relied on the LAN Manager alerter mechanism. Engineers can download the LanMgr-Alerts-II-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LanMgr-Alerts-II-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Windows LAN Manager-based servers/hosts

Monitoring Examples

A management station would configure trap reception for this MIB's alert notifications to catch events such as print-related alerts or service-level faults raised by the Windows LAN Manager alerter service on a monitored host. Receiving repeated alert traps of the same category would indicate a persistent service or print-subsystem problem on that Windows server.
