My suggestion: Write a local IPSec policy on the machine that blocks all to/from SNMP traffic. This should stop the requests every 10 minutes.

What OS is the machine?

There is a machine on our network that is trying and failing to
authenticate with the snmp trap on our core switch every 10 minutes. I can
not seem to isolate what is making the requests. Based on scans that I have
run, there is no know malware (nothing detected anyway). No services running
appear to stop the requests after being turned turned off, and after
installing a host based firewall and reviewing the logs, as well as running
wireshark and reviewing a 2 hour capture, I can not seem to pin point
anything making requests to that switch at all. It is the only machine on
the network of about 900 that is doing this.

I want the machine removed so that I can investigate further, but I am
getting resistance from the IT Manager and support (no time.. not
necessary..). Has anybody seen this before? Am I wrong to want this removed?

Thanks in advance.
