OK
So I changed the Host from a "servername" to a "fully qualified domain name" in the nxlog conf file.
This reduced and/or eliminated the extra windows events coming from the nxlog.exe.

Module om_tcp
Host hnapxlamslog01
Port 3515
Exec $tmpmessage = $Message; delete($Message); rename_field("tmpmessage","message");
Exec $raw_event = to_json();
# Uncomment for debug output
# Exec file_write('%ROOT%\data\nxlog_output.log', $raw_event + "\n");
</Output>
AFTER
<Output out>

Exec $raw_event = to_json();
# Uncomment for debug output

</Output>
