I've installed SNMP on my environment of Windows Server 2003/2008 and configured with group policy to allow our monitoring system to SNMP READ and TRAP with our custom community string. I have a handful of servers that are failing in the monitoring system with no response eventhough they appear to be configured and running.

What Windows-based tools can I use to troubleshoot connectivity and configuration? I would like to do things like SNMP ping, get data (snmpwalk?), or force a trap.


Verify that the server is listening on the SNMP port (161): netstat -an |find /i "listening"

Unofficial Windows net-snmp binaries: http://www.elifulkerson.com/articles/net-snmp-windows-binary-unofficial.php

Provides standard tools like snmpget and snmpwalk.

snmpwalk -v 1 -c community-here

I'd recommend first verifying locally on the server that SNMP is working before continuing to troubleshoot on your monitoring clients. ...


Under Firewall Rules, Inbound Rules, SNMP Service (UDP In) w/ profile Private,Public the Scope defaults to the "Local subnet" which may not be the same subnet as your monitoring server.

Adjusting this rule worked for me.


To add to brent's answer I have recently discoverd Getif which facilitates some SNMP verification as well as other network related tasks.
