Hello. I have a process on my computer that is sending out UDP network scans to every address on 192.168.1.x and 192.168.2.x. The packets are on random ports and continuous. I noticed it on my router log. What software can I use to attempt to detect what process is sending the scans. It does not happen in safe mode with networking. I killed most processes and the scan continued. Please advise the best course of action.

THANKS!! I knew there had to be a tool to do this. Awesome program. Pointed out the process in 5 minutes. Just an FYI for the group, it was the Canon IJ Network scanning tool. This app sends UDP packets out to the device to tell it the computer is available to receive scans. It polls every 3-5 seconds even if you are on a different subnet. My home network is 192.168.2.x and at work it is 10.10.10.x. So it polls for a scanner it will never find. Gotta love this well written software! Be aware to turn off the network scan tool if you are not using it.

Thanks again.

Jerry
