We are currently implementing it at American, but we have not experienced problems (yet) with the windows updates settings, though we have experienced problems with several AV vendors that are on the default allowed list. Good resources to check with would be the ResNet forum (RESNET-L () LISTSERV ND EDU) and the Perfigo and CleanMachines discussion list (PERFIGO () LISTSERV MUOHIO EDU). If I remember correctly, there has been some discussion of windows update problems in the past few days on one or both of those lists. If you can, please file a bug report with Cisco (I've filed at least 4 in the past two weeks) as their out of the box reliability and documentation need some serious work.

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
