guessing your PCs are Windows machines..
if you run netstat or download Active Ports you can see what process
is
sending on that port..
Some kinda multicast packt storm you have going on...

Hi all.. I am new to Ethereal so please excuse my lack of knowledge. I
am
also unsure if this is the right list for this kind of question, if not
can someone point me in the right direction??
A slow network lead me to install Ethereal and see if it could find the
problem. When I did the first capture I saw 70% UDP packets all of
which
looked like the following:-
Source : 10.0.xxx.xxx (most PCs on our network)
Destination : 232.47.16.89 (always)
Protocol : UDP
Source port : 1117 (appears to be random, not always 1117)
Destination port : 47713 (always)
Length 71
Can anyone help? I have slowed it a bit by implementing filtering on
our
switch but while that stops the broadcasts it still slows the PCs. No
viruses or spyware found either.
I have attached a text file with 2 packets exported from Ethereal.
Thanks
Paul
