It was weird, the wired interface wasn't misbehaving. The machine has since been reimaged. I'll ask the workstation support person what virus/worm was found if anyone is interested?

I don't think Clean Access would have helped much anyway - since it would have quarantined the user on wireless, not wired. I agree that if a user is associated to an AP, but not attempting to Authenticate, there should be some mechanism either in the AP's (not likely) or in CCA that, after a period of time, drops/blocks/moves the user. Im actually going to have to think about this one, as I am about to start looking at configured our CCA solution for OOB Wireless/Wired. (currently, we use in-band for VPN access only.)

Food for thought... We had an unauthenticated client machine on the wireless network, using wired, but associated with an AP and holding a DHCP IP address. For hours that machine was conducting little raids here and there trying to compromise user accounts. Once blocked in the Filters, activity ceased. What I was trying to accomplish was if the client machine was holding an IP but not authenticating, I wanted to send them to Quarantine or anywhere after ten minutes. How were they able to conduct the raids, the authentication ports are open to the AD controllers in the Unauthenticated Role...
