Clean Access & Firewalls

No Cisco Clean Access login screen

The Clean Access Agent is required to be installed on all residential computers in order to have internet access. Every time you turn your computer on, the Clean Access log in screen will come up. If the Clean Access screen does not come up you cannot login to Clean Access and thus cannot log onto the internet.

When you try to login using the icon in the system tray in the lower right hand corner of your screen the following errors occurs: Clean Access server is not available on the network. This happens because of a firewall present on your computer. To resolve this issue

  1. Disable your windows firewall.   "How to disable Windows firewall".
  2. Uninstall third party firewalls.    "How to uninstall third party firewalls".
  3. Restart your computer

If the Clean Access login window still does not pop up please call the Help Desk at ext 7575

Enabling/Disabling Windows Firewall (Windows XP only)

Firewalls help protect your computers against hackers but an improperly configured or malfunctioning firewall can prevent your computer from connecting to the network. Presence of a firewall on residential computers prevents the Clean Access server and the clean Access client from  communicating with  each other resulting in the following error.
Clean Access Server is not available on the network (Important Note: This error can also be caused if you are physically not connected to the network. Please check and make sure you have a good connection to the network before uninstalling firewalls.)

In order to disable the windows firewall (Windows XP ONLY)

  1. Go to My Computer -> Control Panel -> Network connections
  2. Select pick a control panel option
  3. Select Network Connections
  4. Right Click Local Area Connection
  5. Click Properties
  6. Click Advanced Tab
  7. Click Settings
  8. Select the OFF or ON radio button to turn off/on the firewall

Uninstalling third party firewalls

Firewalls are designed to help protect your computer against hackers and NOT viruses. Firewalls are not required to be installed by USP policy and in some cases cause conflicts with Clean Access client. Presence of a third party firewall prevents the Clean Access server and the Clean Access client to communicate between each other resulting in the following error: Clean Access Server is not available on the network

Important Note: This error can also be caused if you are physically not connected to the network. Please check and make sure you have good connection to the network before uninstalling firewalls.

In order to uninstall third party firewalls:

  1. Go to My Computer ->Control Panel -> Add or Remove Programs
  2. Find the desired firewall that needs to be uninstalled.
    • For computers running Norton it is usually: Norton Internet security.
    • For computers running McAfee it is usually: McAfee Internet Security.
  3. Select the item needed to be uninstalled.
  4. Click Remove.
  5. Click Remove All.
