<p class=MsoNormal>I believe I have something similar to this: <a

<p class=MsoNormal>I was first trying to troubleshoot a problem with Offline
Address Books not downloading on our Exchange server. When I ran wireshark on
the Exchange server and my workstation(windows xp), I saw significantly less
traffic on the server.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Today I was trying to troubleshoot and LDAP problem against
a DC from a Multifunction Copier. Running wireshark on the server, I was only
seeing the threeway handshake and then the ldap bind request. There were no FIN
or RST sequences. When I hooked up to the SPAN port I saw the entire TCP stream.<o:p></o:p></p>

<p class=MsoNormal>The other user in the linked message above reported
having a Broadcom BCM5708C chip. Maybe the drivers / new chimney code is
causing shenanigans that aren’t visible.<o:p></o:p></p>
