SNMP is installed but there are no traps set and as far as I can tell it is not configured to check anything.   I do not have a lot of software installed on this server except for the Xerox XDA agent to monitor our printers.   I see no reason why it should be communicating with this IP address.

There are a lot of the 4653 events in the security log as Audit Failures to several different IP addresses.

I am running Windows 2008r2

SNMP as a service has a read-only and change phrase like "public" and/or "private".

SNMP Trap Service under (services.msc) is by default there for sending traps to SNMP collectors like Tivoli or HP MOM.  

The source of that "error" above is your Audit settings under local policies or GPO.

Click Start - Run - type "gpedit.msc"
Local Computer Policy
Windows Settings
Security Settings
Local Policy
Audit Policy

The answer to your question, I think, is this has nothing to do with SNMP but instead local Windows Auditing Policies and this is more granular depending on what you have installed on 2008R2.

For example, Start - Run - "eventvwr.exe"

Applications and Services Logs (not Windows Logs)
There are 100's of logs here.
SNMP is made up of two components. The notifier, snmptrap service, when configured will generate SNMPTRAP events. and the SNMP service that allows polling. Within the SNMP service configuration you should have manager defined meaning only the managers can query the SNMP service for data.

Along the same route, you have evntwin which is a tool to configure the event log to SNMP TRAP event.
i.e. when a specific event log entry is added, a corresponding SNMP trap is sent.

Now the issue reported to you is likely from an SNMPTRAP monitor that converts the received events and converts them into emails.

Now the error says that an SNMP poll from was seen on the system

Event you posted was a IKE meaning IPSEC access and not SNMP.

Check the full message headers of the email to determine the server from which this email originated, then look at the configuration to make sure the SNMP trap to email converter is configured properly to generate the correct email notice.

I think I narrowed it down to the Xerox XDA service.  It started a poll from 10:02 -  10:05 and I received the messages between 10:03 and 10:04.  

The device sending the emails is not a server and only has a web interface which I was unable to connect to to verify the settings.    

The SNMP reference in the email threw me off as I have no SNMP traps configured on this server.
The snmptrap is the recipient of events.
What generates the notice and what is its process is it akin to splunk that aggregates and processes event logs?
