Although the error states that the service is unavailable more often than not this type of error code can be caused by anything from your Internet connection to configurations in applications on your PC. The best way to troubleshoot is by starting with the basics.
Make sure the time and date is set properly on your PC. You can check this by double clicking on the time in the lower right hand corner of the desktop screen. If the time and date are not correct make the necessary corrections and then try to sign in to Messenger again.
If you are using a third party firewall such as Norton Internet Security it may be blocking the Messenger program from access to the Internet. In this case it may be necessary to add Windows Live Messenger to the list of allowed programs in the firewall list. You can also try disabling and then re-enabling the firewall application and then try to sign in to Messenger again. If you have disabled the firewall to troubleshoot other problems in the past, this will help to ensure the firewall is not the cause of the problem.
If you are still experiencing difficulty signing in to Messenger it may be necessary to re-register DLL files. You can do this by clicking on Start
on the main toolbar and then choosing Run
from the menu. When the command prompt opens enter regsvr32 softpub.dll
and then press the Enter
key. Repeat this procedure for each of the following files: regsvr32 initpki.dll regsvr32 wintrust.dll
and regsvr32 MSXML3.dll
and then try to sign in to Windows Live Messenger again.
You can also try to correct the error by checking the settings in Internet Explorer. Open Internet Explorer and click on Tools
on the main toolbar and then choose Internet Options
from the drop down menu. Click on Advanced
and then choose Security
. Remove the check mark next to Check for server certificate revocation
if a check mark is present in the box. Verify that Use SSL 2.0
and Use SSL 3.0
