FYI for the list: We've been using a product called Campus Manager to the past few years from Bradford networks, www.bradfordnetworks.com <http://www.bradfordnetworks.com> they're a small start up in NH but they've been growing and have an awesome product that sits off line and is very flexible in what it can do based on what you want/need. It does both network registration and remediation/quarantine functions. It's worth looking into if your looking for a solution. We've been very happy with it. Mike Michael A.

Anyone pilot both CCA and Impulse Point ( http://www.impulse.com/ <http://www.impulse.com/> )? Impulse Point was designed for higher ed and is priced very attractively. So far, we've only seen presentations and nothing live. Any feedback would be great.

This is a response from our network lead who implemented CCA a month or so ago: I got tired of trying to keep up with the IP's used for windows update. Using the host names is much better, but even then it's a moving target. Microsoft sometimes adds new sub domains and in the latest version of the update page it's a url under microsoft.com. We are allowing traffic to everything ending in microsoft.com and g.msn.com. That way the updates always work (so far) and students can search for and download patches manually. There are cases when windows update claims that a machine is fully patched but it is still missing something. The helpdesk can tell what's missing from the reports and the student can search for KBxxxx and download and install it manually.

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
