This page provides troubleshooting procedures for common MLS communication problems, but does not address all possible problems or procedures.

Troubleshooting questions

Consider each of the following questions in order as you troubleshoot your MLS communication problems.

Is this a new computer?

  1. Yes: Go to the next question
  2. No: Go to Did you get a security failure? question

Has the computer ever transmitted successfully?

  1. Yes: Go to Level 1 troubleshooting
  2. No: Go to the next question

Have you already installed Sophos Anti-Virus and Anti-Malware software?

  1. Yes: New computers should transmit with MLS before Sophos Anti-Virus and Anti-Malware software should be installed. If Java is being blocked by the Windows/Sophos firewall, holding down the Ctrl key while starting MLS should pop up the Java blocker notification window. You should click the "Unblock" button to except MLS Java from the firewall. Go to Level 3 troubleshooting and check for the firewall.
  2. No: Go to the next question

Did you remove or uninstall the Digital Line Detect?

  1. Yes: Go to the next question
  2. No: Go to the Add or Remove Programs in the Control Panel and remove Digital Line Detect. Go to Level 3 troubleshooting and check for the firewall.

Did you get a security failure?

  1. Yes: Contact the Church administrative office to reset security.
  2. No: Go to the next question

Does the transmission fail when “verifying username and password” or when “transmitting data” and then starts dialing again?

  1. Yes: If the error message is an Afaria error, go to Level 2 troubleshooting. If it shows the Three possible problems… error, go to Level 1 troubleshooting.
  2. No: Go to Level 1 troubleshooting

Did you make any changes to the computer or install any kind of software?

  1. Yes: A problem typically occurs if another modem is installed. If a cell phone is used as a modem to transmit data, it installs a modem that needs to be removed before the computer can transmit data to the administrative office.
  2. No: Go to Level 1 troubleshooting

Level 1 troubleshooting

Phone lines

Check the phone lines, modems, firewalls and wireless routers. Be sure they are all connected properly. If the unit is using a dialup modem to transmit, check the phone line and listen for excessive static. If there is excessive static, contact the FM group. They should work with the phone company to clear the lines for modem transmissions. The best way to test whether the telephone line is interfering with the transmission attempts is to take the computer to another clerk's office where a different unit's computer is successfully transmitting. Plug the telephone cord coming from the line/wall side of the modem on the non-transmitting computer into their wall jack and try to transmit. If transmissions are successful there, the original telephone line should be repaired or filtered properly to correct the situation.

Dialer numbers

The dialer numbers are located in System Options in MLS. Click on the System tab to the left to verify the information is correct.

  1. The area code field is not used to dial, but is a place holder. It should have the area code from which you are dialing, if populated.
  2. Verify the dialer number. If there are two numbers they should be separated by a semi-colon. Also, there should be no spaces or dashes between individual numerals.
  3. Verify that the Dialer Script is checked ignore and MCI is selected, for US and Canadian locations.
    • If MCI is not selected, remove the checkmark from the Dialer Script. Click on Select and choose MCI. Click OK and put the checkmark back in the Dialer Script Areas outside the Us and Canada should use the correspondent script required for your area.
  4. If any changes were made, click Save at the bottom and then Close.
  5. Do a Send/Receive Changes. If it still will not transmit, continue to Level 2 troubleshooting.

Level 2 troubleshooting

  1. Close MLS.
  2. Go the Start Menu and open My Computer.

  7. Open the Network Connections.
  8. Delete the MLS dial up (connectoid).
  9. Shut down the computer.
  10. Turn on the computer, sign on to MLS and do a Send/Receive Changes.

Level 3 troubleshooting

If the unit computer is running Windows XP Service Pack 2, check the configuration to see if the Windows Firewall is blocking the communication of Java and MLS.

  1. Close MLS.
  2. Hold down the Ctrl key and double-click on the MLS icon.
    • This will bring up a black dialog box, the MLS screen, and possibly a third box that contains the following message:

"To help protect your computer, Windows Firewall has blocked some features of this program. Do you want to continue blocking this program?" Three options are given: Keep Blocking, Unblock and Ask me later.

  1. Choose Unblock.
  2. Close the windows, then reboot the computer.
