event viewer

I am having the same problem
Windows cannot display the properties of this connection.
The Windows
Management Instrument (WMI) information might be
corrupted. To correct this,
use System Restore to restore Windows to an earlier time
I reinstalled XP Home Edition, from the boot CD still
having the same problem can't even view the Events log
also when I try to start the sevice WMI I get this
message "Win32 dependency service or group failed"
Tried the repository clean up still does not work
What else if someone knows I would greatly appreciate.

Thanks
Marc.
