Martin, We have the same product, and I think we got around this by allowing 8 minutes of network access for machines that fail scanning. This gives enough time to download OS & AV updates before the system kills the connection, necessitating a reboot or re-login (sorry, I can't recall the specifics). - Charlie. -----Original Message----- From: Flagg, Martin D. [mailto:FlaggMD () HIRAM EDU] Sent: Thursday, July 14, 2005 2:13 PM To: SECURITY () LISTSERV EDUCAUSE EDU Subject: [SECURITY] Windows Updates and Cisco Clean Access We are implementing Cisco Clean Access (formally Perfigo). It has gone really well but we keep coming up with problems with Windows Update, it fails because CCA is blocking the IP. When this happens, I use a sniffer and add the new IP address that Microsoft is using and then it works, until they change address's again. Cisco says use the Host setting allowing requests that end in "update.microsoft.com". This does not always work. I am really at a loss because it works for 95% of the machines but I can not afford to have 5% of the students in my office when they get back from the summer. Any Ideas? Martin Flagg Hiram College
