Firewall

The Firewall component of Norton Internet Security or Norton Personal Firewall products must be configured to allow desired programs to run over the Internet. The firewall should be set to "Allow" or "Permit All" (not set to "Auto" or "Custom") so that  programs such as CTI Navigator and CTI Update Manager will be allowed to send and receive MLS information over the Internet. Normally a Norton security product automatically detects the first time a new program attempts to access the Internet and then prompts you to allow or block access. Always "allow" CTI Navigator functions. Otherwise, you may need to manually configure the program rules in your Norton product. 

To configure a program rule in Norton 360 "All-in-One Security" to allow CTI Navigator functions to access the Internet:

  1. Start Norton 360
  2. Click Task & Settings at the top of the main menu
  3. On the Task & Settings menu click Advanced Settings
  4. On the Advanced Settings screen click Firewall Protection Settings
  5. On the Firewall Protection Settings screen, click the Firewall Program Rules tab
  6. Select CTI Navigator (and/or CTI Update Manager) in the list of programs
  7. In the Access column beside CTI Navigator (or CTI Update Manager), click the down arrow and select Allow (not Auto or Custom) 
  8. Click the Apply button at the bottom of the screen.

Internet Worm Protection

If you are running Norton's AntiVirus or SystemWorks (by Symantec), you can add programs (such as CTI Navigator and CTI Update Manager) to be "permitted" to run through Norton's "Internet Worm Protection" as follows:

  1. Open Norton Protection Center (right-click on Norton's icon in the system tray)
  2. Click Options (at the top). Click Norton AntiVirus if you see a menu
  3. On the left pane, select Internet Worm Protection
  4. On the right pane, click Program Control
  5. Click Add
  6. Locate the program executable for the program that you would like to add a rule for (Cti Navigator.exe and CtiUpdateManager.exe). If you have other programs that you want to configure, then repeat steps 3-5 for each program.
  7. At the next dialog box, from the dropdown menu, click Permit.
  8. Click OK.
If the above does not work, turn off the Norton Internet Worm Protection. If you are running Windows XP with at least Service Pack 2 (which includes a Windows Security Center), you may want to activate the Windows firewall (as described in the related article Configure Security Settings in Windows XP and Vista) to serve as protection when Norton's Internet Worm Protection is turned off.
