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
