Odd message thread on bootup

Greetings!

Windows XP home edition with SP2. Computer boots to logon prompt with this string;
c:\windows\system32\wlnotify.dll.
This same string repeats itself after entering password, then system continues to bootup. This has only recently begun happening. What is it?

Thanks in advance for any help!
Bill

 

The library file wlnotify.dll, is required by windows and is used to handle WinLogon related events such as LogOn, LogOff etc. Windows will not work, if wlnotify.dll is unavailable.

wlnotify.dll is related to msgina.dll.
