Hello,
Today I discovered what might be the reason for CAD being
so slow in Windows 2008, Vista or Windows7 when we are in
the Logon screen.
Please read carefully:
CAD.exe is signed by Rudi with a cert from Globalsign
E = rudi.de.vos@skynet.be
CN = uvnc bvba
O = uvnc bvba
C = BE
CN = GlobalSign ObjectSign CA
OU = ObjectSign CA
O = GlobalSign nv-sa
C = BE
Now, here is the interesting part:
If ou are behind a corporate proxy or something
that does not directly allow you to connect to
the Internet site of Globalsign ( 64.18.25.38 ), then
the process consent.exe is trying to check the validity
of the CERT and uses this site to see revocation lists etc.
This poses a great deal of SYN_SENT towards the site
to port 80 until the site web server responds with the
necessary data. Please check http://64.18.25.38
We can monitor this with TCPview from Sysinternals.
Until the site responds or the consecutive Web requests
return or timeout, CAD.exe is not getting executed.
After all unsuccessful requests timeout, CAD.exe is fired up
and Control Alt Delete is pressed...
Hope I helped .
