I have experienced this with the Clean Access Agent in these three cases: * Norton's or McAfee endpoint security suites which incorporate firewalls, proxies (for ID protection), and application controls. We had to uninstall to verify it.
* The switches have ACLs that prevented UDP ports required by the Clean Access Agent to communicate with the server. * In rare instances, the MAC OSX 10.6 firewall. Standard troubleshooting applies: * Can you ping the CAS? * Can you get to the CAS via the web browser? (Redirected to an authentication or agent download page) Hope this helps.
