My computer is sending a UDP packet to our firewall every 2 minutes unless Zonealarm is on. Any ideas? I'm running XP Pro.

Thanks,

Russell
 
Did you log/snif the packet? IT might be anything from a "hey, i'm still connected" packet to pretty much anything unless you give us more information.

I don't know where/how to log or snif the packet. The way this was discovered is in the router (Sonicwall) log. My IP is shown as the source and our router IP is the destination. The message is: Denied UDP packet from LAN.
My machine is the only one that is sending out a package every two minutes. What other info do you need? I ran an updated Norton Anti-virus scan and found nothing. Also I ran Spybot S&D and got rid of one ad cookie.
 
It looks like MSN messenger has something to do with this. I disabled messenger and unchecked it from the Window Components... it still sends the UDP packet every two minutes unless I have messenger blocked in Zone Alarm.
Clues?
 
In Zone Alarm it refers to a "messenger" so I guess it's windows messenger. In 'control panel> admin tools> services> there is a "messenger", I have that service disabled. I'm not using msn messenger. So I'm pretty sure it's windows messenger.
 
So messenger is sending out packets about every minute. Is this normal? Any clues?
 
Windows Messenger may repeatedly try to log on to the Microsoft .NET Messenger Service in the background, and when Windows Messenger cannot log on, no error messages are generated.

This problem may occur if Windows Messenger tries to log on to the .NET Messenger Service by using an incorrect password that was saved. For example, this may occur if you click the Sign me in automatically option when you log on to .NET Messenger Service with Windows Messenger and then change your password on the Passport Web site.

To resolve this problem, upgrade to Windows Messenger version 4.6.0077 from one of the following Microsoft Web sites:


This update is located in the Critical Updates section of the Windows Update Web site as "Windows Messenger 4.6 Connectivity Update."

This update addresses several security and service reliability issues in Windows Messenger 4.6. To improve connectivity and system performance, even if you do not use Windows Messenger, Microsoft recommends that you install this update.


When in doubt, deny all terms and defnitions.
 
You do not state which operating system you are using.
If you are using Windows 2000/XP it might pay to disable the messaging service.
But in order to advise you we need a little more information.

Sorry I missed the first post in the list.
Open the control panel, goto Administrative tools, open the Services console. Search down the list until you find the Messanger service, right click on it select properties and stop it. Does this stop the udp packets. If so I would suggest leaving it stopped and setting the "Start up type" to either manual or disabled. If you think you might need it in the future (very unlikely unless you are attached to a corp network) choose manual otherwiase choose diabled.

A good list of operating system services, what they do, what you need and which can be safely disabled can be found at
 
fredsnothere - does your name refer to the resturant in Toronto? Supposed to be pretty famous, if I remember correctly it is on King Street, or thereabouts.

When in doubt, deny all terms and defnitions.
 
I had Messenger disabled in the 'services console.' It still pinged every two minutes. Finally I found a microsoft blurb about "How to Prevent Windows Messenger from Running on a Windows xp-based machine." This showed me how to alter the registry and thus stop the pinging. Thank you though, for your interest and input, Viol8ion and Fredsnothere.

DNS uses UDP, you may be getting DNS requests. Or another common UDP request is port 123 (NTP) Network Time Protocol . receiving updates in time on your server(s).
