Error Code 80072745: Unable to sign in to Windows Live Messenger

Asked By 1660 points N/A Posted on -

Hi folks and friends, I am posting here an image of an error message, I encountered this error message when I sign on to Windows Live Messenger Beta.


Windows Live Messenger

We were unable to sign you into Windows Live Messenger Beta, possibly because of a

 problem with your Internet connection. Please try again later.

Windows Live Messenger has made several failed attempts to sign you in . Your

 firewall may be blocking Windows Live Messenger from connecting to the service.

 Please review your firewall settings. See the retailer’s  instruction for more


Error code:  80072745

When I read the instruction on the error message, it tells me to check my internet connection, as I am checking my internet connection, there is nothing wrong with my connection, I also check on my firewall, there is no restriction on the connection for Windows Live Messenger Beta, that is why I am wondering what other reasons that lead to this error, please help me find solution to my problem, thanks a lot for reading my post.

  • Good day to you Steve. When you get an “Error code:  80072745” when you try to sign in to Windows Live Messenger, in most cases it is caused by firewall or security software in your computer. Turn off your security software for awhile and see if you can login to Windows Live Messenger. If it works, then you need to grant access to Windows Live Messenger in your security software so that it will not block it next time you try to login when the security software is turned on.
  • Now, if turning off the security software doesn’t fix it. You need to check if it’s the router. Router’s these days have a built-in GUI (Graphical User Interface) where you can specify settings according to your needs. If it’s not much of a hassle, you can try to bypass the router and connect the modem directly to your computer. Login to Windows Live Messenger and see if you can connect.  If you can connect to Windows Live Messenger without the router connected. I suggest you change your router settings and before you do that make sure you know how to do it according to who and how your ISP’s configuration. You might have to call them if the need to change the router settings arises.

Hello Steve,

  • Is everything else is opening and working ok or not. You must check your modem driver. Is it working properly or not or you have to update it. Then unplug the wire of internet and restart your system and plug the wire again. Connect internet and use to hear the dial tone on your landline phone set while you are connecting the internet. Otherwise you should check the MSN messenger files. Maybe some file is corrupt which is causing this problem.
  • You can manually fix the problem too. Check the IM Security settings of your MSN messenger and go to main tab and go to slider to disable IM Security settings. Restart your system and then check again. If that is causing some trouble in normal mode then you can perform this task in safe mode. Or else you have to reinstall the MSN messenger.

Error code “80072745” is a known issue in Windows Live Messenger which is usually caused by a problem in the internet connection or the setting in Windows Internet Explorer. If you encounter this error, the problem could be with your internet connection so try troubleshooting your connection. If your computer is connected to a Wi-Fi router with a network cable, disconnect the cable from the network port then plug it back in.

If this doesn’t work, disconnect the other end of the cable from the Wi-Fi router then connect it back. If this doesn’t work either, restart the router. If the router has a power button, press it to turn it off then unplug it from the power for about twenty (20) seconds. Press any button on the router to discharge any leftover power or to power cycle.

After this, plug the router back to the power and turn it on. If this doesn’t work, start Windows Internet Explorer then go to “Tools” then select “Internet options.” In “Internet Options” screen, go to “Connections” tab then under “Local Area Network (LAN) settings” section at the bottom, click “LAN settings.”

In “Local Area Network (LAN) Settings” dialog, uncheck “Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections)” then click “OK.” Back to “Internet Options” screen, go to “Advanced” tab then scroll down to “Security” section. Uncheck “Check for server certificate revocation.” Check “Use SSL 2.0” and “Use SSL 3.0” then click “OK.”
