Issue that is fixed
SNMP Trap registration fails when the SNMP Trap port is in use because of a previous registration. This issue has been fixed to make sure that SNMP Trap is not re-registered by using the port.
Download the SNMP Modules self-extractor.
Extract the contents of the file to a local folder.
In the service console, stop the HealthService (Microsoft Monitoring Agent) service.
Make a backup of the existing SnmpModules.dll file from C:\Program Files\Microsoft System Center 2016\Operations Manager\Server\SnmpModules.dll.
Copy the extracted SnmpModules.dll file to C:\Program Files\Microsoft System Center 2016\Operations Manager\Server.
Restart the HealthService (Microsoft Monitoring Agent) service.
