A friend sent me this tonight and it may answer your problem: "A certificate which Verisign used for signing SSL certificates has expired. When applications which depend on that certificate try to make an SSL connection, they fail and try to access crl.verisign.com, the certificate revocation list server. This has effectively DOS'ed that site, and Verisign has now updated the DNS record for that address to include several non-routable addresses, reducing the load on their servers. Some applications affected include older Internet Explorer browsers, Java, and Norton Antivirus (which may manifest itself as Microsoft Word being very slow to start)."

Hi guys, I have a problem with a site .. 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 .. 198.49.161.200 - 198.49.161.205 - 198.49.161.206 However, if the Network cable is disconnected, the Excel and Word files open faster ... with no connections attempted to crl.verisign.com .. Anyone have any idea what could be the cause ? Thanks in advance .. Naren --------------------------------------------------------------------------- Ethical Hacking at InfoSec Institute.
