My version of Windows Live Writer wasn’t pinging all of the sites on my blog ping list. Turns out Windows Live Writer has an extensive logging capability. To access the WLW logs enter the following at a command prompt and it will open the Windows Live Writer Log in notepad:

%userprofile%\Local Settings\Application Data\Windows Live Writer\Windows Live Writer.log

Turns out some of the ping servers just weren’t responding:

WindowsLiveWriter,1076,Fail,00073,19-Sep-2006 22:01:47.531,”Failure while pinging http://ping.rootblog.com/rpc.php: System.Net.WebException: The remote server returned an error: (404) Not Found.
