After I log into the wireless network, why doesn't the NAC Agent pop up?

Please check following items for this problem:

• Make sure the NAC Agent is running. You should see the NAC Agent icon in your system tray. You can manually run the NAC Agent by double clicking the NAC Agent icon on your desktop.
• Right-click the NAC Agent icon in the system tray and make sure the Popup Login Window option is checked.
• Make sure the NAC Agent is not blocked by the Windows firewall or other personal firewalls.
