You can find the complete capturehere. He also took avideoto help synchronize what happens on the screen with the trace (we removed the audio to help keep my friend anonymous). If you don’t know Wireshark and want to follow along you should probably look at some tutorials first. What ...
I think that short of having Wireshark constantly logging frames on the VLAN, waiting for the problem to recur, then reviewing the capture to see who/what is generating an absurd level of traffic, I won't get to the bottom of this. I had thought that this problem had occu...

Have you verified the DNS update message format in the netmon trace / wireshark trace ?, i am more interested in the return code flags of the packet. which is i guess 0x8 as you mentioned earlierHave you done any windows upgrade on windows 2003 server ?
Using wireshark I can capture/inspect packets with 2 different VLAN IDs on my network. I was hoping to suppress packets associated a particular VLAN ID. So, using the ethtool I added a hardware filter as follows: sudo ethtool -U eth11 flow-type udp4 vlan 0x65 vlan...
This was the case in my experiments with Wireshark running on Windows. That message was sent by wsdd using unicast and thus Windows can compare the IP-layer sender address with the IP address provided in the "ResolveMatch" message body. A smart implementation may now detect a mismatch ...
