Resolve Error Code 80072 efd and Error Code 0x81000370

Error code 80072 efd and error code 0x81000370 may be generated when you attempt to sign in to your Windows Messenger.

Cause of the Error

Normally, these error codes are generated if the .NET Messenger service is having a problem. This means that one or more servers that are providing the service are either down or are facing some operational problems, thus preventing you from signing on to the service. Quite often, this problem gets resolved by itself in a few minutes or a few hours.

In the meantime, you may try to connect to the Web Messenger facility to log in to the service.

Resolution Methods

At times, the error codes may also be generated due to some other problems. A list of a few corrective actions that you can perform in order to resolve the issue are discussed below:

  1. Check System Date and Time Settings: If the date & time setting of your system is incorrect, you will not be able to sign-in to Windows Messenger. To set the correct date & time, double-click on the clock given on the right corner of the taskbar and then on the Date & Time tab set the correct date and time.
  2. Ensure that you are entering the correct Username and Password: MSN errors generate if you enter an incorrect password during sign up. Make sure that your caps lock is not on and the password is entered correctly in the box.
  3. Try to Change your Login Password: Open Windows Live Web site and use the “Forgot your password?” option to reset your password. Try to use a smaller password this time to make it easier to remember.
  4. Check your Firewall Configuration: If you have a firewall program on your computer, check its settings. It is quite likely that the firewall settings are preventing Messenger from accessing the Internet. This usually happens when you upgrade your current messenger to the latest version. To resolve the issue, you may be required to add Messenger to a list of “allowed to access Internet programs” in your firewall.
  5. Uninstall any disabled firewalls installed on the system: Even a disabled firewall may block Messenger from accessing the Internet. If this is happening, then it is best that you uninstall the firewall software. You can do this by using the Windows Add or Remove Programs utility or a third-party program uninstall, such as Perfect Uninstaller.
  6. Clear cache and cookies: Open the Internet Explorer windows, on the Tools menu, select Internet Options. Click the Delete button. In the Delete Browsing History dialog, first click the Delete Files button and then the Delete cookies button.
  7. Verify Internet Explorer Security Settings: Open the Internet Explorer windows, on the Tools menu, select Internet Options. On the Advanced tab, go to the Security section, and ensure that:
    • The Check for server certificate revocation check box.
    • The Use SSL 2.0′ and Use SSL 3.0 is selected.
  8. If the settings are not as desired, change them and then click the OK button.

    Note: Internet Explorer steps covered here are for Internet Explorer 7.
