RE: SNMP Traffic over spoolsv.exe ?

  HP loves to use SNMP to talk to their networked printers,
presumably from within the printer driver code which spoolsv
would be likely to call.

Subject: SNMP Traffic over spoolsv.exe ? 


This seems odd.... Snort is reporting every 5 minutes one of 
our internal PC's generating SNMP traffic to a private IP 
that is not part of our network. The thing is , SNMP isn't 
running on the system and the source port is coming from 
spoolsv.exe (print spooler). Here is a verbose of tcpdump, any ideas?

08:56:02.499840 x.x.x.x.1159 > 192.168.0.150.snmp:

Here is snort output
