I have a question about NAC & Windows Logon. I currently have a Cisco 3560 as the Network Access Device. Cisco ACS Solution Engine is running 126.96.36.199(3) for my ACS Server. I'm doing internal posture for Active Directory Auth, and External Posture for Trend Micro AV. Clients have the CTA + Supplicant installed.
When I logon to Windows upon booting up I'm placed into the quarantine vlan and on the NAD (3560) the log shows CiscoTrustAgent Not Detected. If I disconnect cable and plug back in, everything works fine...my posture comes back healthy, I'm authenticated, and placed into the correct VLAN.
Any idea why it is different first logging into windows versus plugging in after logging in?
