do you have a physical access to your collegue's system? why not search for the sending program there?

i didnt understand.
is there any program from my collegue's pc is trying to contact our server?
he is using winxp.

yup. that's what i mean. try fport from foundstone to find listening programs. you might also simply do netstat. it can even be the windows xp itself. try to turn off the snmp querying in windows. the bad thing is i really don't know if windows have snmp querying and i don't know how to turn it off.
