14. click OK or X to close
15. Re-start your computer.

If the error persists, configure, temporarily disable or remove any Internet Security program, Internet Accelerator, or Internet Proxy Service. If disabling or removing a third party program unblocks CTI Navigator's Internet functions (allowing them to work), contact the vendor of the security or accelerator program for instructions on how to configure their program to always allow CTI Navigator.exe (and CTIUpdateManager.exe) to access http://ctimls.com over the Internet. 

To configure security in Windows XP and Vista, follow the instructions in the related article below entitled "Configure Security Settings in Windows XP and Vista." Note that security settings in Windows will not override security settings in third-party programs (such as Norton, McAfee, or ZoneAlarm firewalls) which may need to be similarly configured. 

 If setting DCOM does not fix the error, follow the instructions to use the SOAP Patch to Bypass DCOM (below). 

If needed, also see the related article below to "Fix Error RPC Server Unavailable" errors.

SOAP Patch to Bypass DCOM

If you are still unable to log into CTI Navigator over the Internet or to send information from your computer to the MLS server (such as listings, photos, or Matchmakers), run the following SOAP patch to bypass Windows DCOM:

1. Close CTI Navigator
2. Go on the Internet to www.ctimls.com/MlsServerNet/Default.htm
3. Click the Install button
4. If a screen appears requesting to close the tab or Window, click NO
5. If an ActiveX warning bar appears in the top section of your Internet browser, click where indicated to "Install ActiveX Control" 
6. If an error message appears that some .tmp file cannot be found, close the message and repeat the preceding steps using www.ctimls.com/MlsServerNet/Disk1/Default.htm as the address
7. At the prompt to install setup from Creative Technology of Sarasota, Inc, click Install
8. If your Windows does not already have a Microsoft's .NET Framework installed, it will be downloaded automatically. This may take 15 to 25 minutes. Vista already includes .Net and will automatically skip this step.  
9. At the prompt, install CTI Navigator.
10. Re-start Windows.

Note: This "SOAP" patch is for use when your Windows DCOM will not work.

Other Fixes (rarely used)

If your computer connects to the Internet through a proxy server or firewall on a Local Area Network (LAN), the local server should be set to use HTTP proxy with SSL Tunneling (over port 80). Otherwise, you may need to temporarily disable your Firewall or Internet Security program.

Warning: Before you modify the Windows Registry, it is advisable to back it up and ensure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, read the Microsoft Knowledge Base article, Description of the Microsoft Windows Registry (see the related article link below). 

If the CTI Navigator function currently incurring error 462 previously worked on this computer and all other approaches to fixing the error have failed (including the SOAP Patch), you can use the Windows System Restore function (in Windows ME, XP and Vista) to reset Windows back to when everything worked correctly. For instructions, see the related article link below, "Restore Windows System files".
