I used to receive the below error message whenever I tried to shutdown windows XP. A rather vexing problem, no doubt.
- Scout service run by Nero 7
- Microsoft Office Communicator 2005
The fix is simple, disable the Nero 7 scout service if it is enabled.
For this, go to Start > All Programs > Nero > Tools > Nero Scout.
On this screen ,Uncheck Enable the Nero scout.
This will fix the issue for most of the users, for the rest of you who are not using Nero are most probably getting this error because of Microsoft Office Communicator 2005. For that you need to either manually exit the communicator 2005 from the system tray before you shutdown windows, or also you can use this hot-fix provided by Microsoft for WMI Idle error message.
