Hi, I'm running XP pro SP2 with all patches applied.

I've recently started getting multiple event log entries (see example
below). They seem to come in blocks of 20 entries, with each entry time
stamped about 20 seconds apart. They occur even when I am not logged on or
using the PC.

A hard drive scan reveals no problem and I am not having any obvious
operational problems. I cannot think of anything obvious that I have done to
prompt their appearance. Any ideas would be appreciated.

Thanks, Steve
