IE 5.5 does not automatically check revocation lists, however when I upgraded to IE6 SP1 this was automatically selected and amounted to a considerable amount of traffic being stopped by our proxy service until I turned it off.

When the PC is connected to the LAN, opening local Excel and Word
files
take abnormally long time .. disabling the AV does not make a
difference
.. and a lot of SYNs are shown to the Verisign IPs of crl.verisign.com

I have been seeing this as well on my XP Box, and may be wrong, but it looks like it has something to do with some kind of "certificate revocation list"? The only way I could so far find to switch it off is to go to IE Tools-> Internet Options-> Advanced, turn off the options that check for the CRL, e.g.. "Check for Publisher's CRL", "Check for Server's CRL", and "Warn about site certificates" BUT I =don't= want to do this, as the check in my view is needed for IE. What annoys me the most is that this outbound checks happens everywhere you go; Windows explorer, Word, Excel, MS Project ... The amount of traffic this generates with ordinary PC usage is enormous and automatically happens when you're online. I'd hate to be a dial-up user! Oh yeh, and if you block it using your firewall, opening anything that makes this request makes you wait until it times out... It all started after installing a MS Update .. I have however not yet found the time to look at which one exactly. Anyone else maybe? -Chad ------------------------------------------------------------------------ --- Ethical Hacking at InfoSec Institute. Mention this ad and get $720 off any course!
