In my new Lap top (Inspiron 1720 with Vista Home premium), the message "WMI provider host has stopped working" appears systematically after booting (and this happens since I got the new computer). If I reboot it may appear again or not, it looks as a random behaviour. After the message, the computer looks working normally (I am using only office and internet), but it is slower to access my home network.

Which is the function of WMI and is it possible to avoid this stop working?

Thanks
