Overview

Wireshark confirms traps are coming into the server, but Orion is still not receiving them.

Error messages can be seen in TrapService.log located in the C:\ProgramData\SolarWinds\Logs\Orion\ folder such as: 
[StartupThread] ERROR TrapService.TrapService - The service is unable to bind to port 162. Please stop the other trap manager.

[StartupThread] ERROR SolarWinds.Orion.Common.SWEventLogging - Service Start Failure. Unable to register with SNMP Trap Service for SNMP Trap reception.
[StartupThread] ERROR TrapService.TrapService - Error stopping service
System.InvalidOperationException: Cannot stop SolarWindsTrapService service on computer '.'. ---> System.ComponentModel.Win32Exception: The service has not been started

Cause

Microsoft's SNMP Trap Service is receiving traps instead of Orion.

Only one trap service can be run on a server at any given time.

Resolution

Microsoft's trap service must be turned off in order for SolarWinds Legacy Trap Service to operate.

1. Click Start > Control Panel > Administrative Tools > Services
2. Confirm that the SNMP Trap Service is Disabled.
3. If the SNMP Trap Service is not Disabled, right-click SNMP Trap Service, and then click Stop.

Make sure to start SolarWinds Trap Service in the Orion service manager after making the changes.
