I’d usually assume this was firewall related at some point in the path, either on the devices themselves or an intervening firewall that’s been tuned to get very jumpy when a lot of UDP gets thrown at a windows system.

Subject: [Observium] Windows SNMP Timeout

Hello,

Is anyone else having any issues with SNMP timeouts on windows servers? I’ve checked the servers to make sure the port is open and it is listening, but whenever I either do the poller or I manually do the snmpwalk I get a timeout. Same thing if I run the snmpwalk from another server. I do get a ping response so I know they can communicate. I have 3 Windows 2012R2 servers that are having this issue, not sure if maybe it was a recent windows update. TIA
