VDS Dynamic Provider -- what program(s) causes this/

During a check of the Administrative Events in the Event Viewer, I happened to notice a cluster of VDS Dynamic Provider errors in the log: "The provider failed while storing notifications from the driver. The Virtual Disk Service should be restarted. hr=80042505"

Searches on the Internet turned up some hits, but isolated to Vista SP1 and Sever 2008. I am on SP2. There didn't appear to be any resolution for it.

With my curiosity prodded, I started looking into my Event history... Sure enough, on April 11th, the first occurrence of this VDS Dynamic Provider error occurred. It has been occurring every day that I use my computer since that date. I checked my installed program list and the only thing noted was on 4/11, Microsoft Office Professional Edition 2003 was updated. I remember there was something I wanted to use in the Office Suite and it required the install disks to get some files. But, I had installed Office 2003 a long time ago without incident.

The event frequency is sometimes a few within the hour, but sometimes once every couple of hours for the duration of my using the computer. I'm just wondering what is going on, if there is some background activity thrashing about and failing. I'm presently on the hunt to try reducing my resource load, so every little bit I can cut back on will help.

Look at this and see if it helps-
Internal Server Error

Thanks. I had seen that thread, and it appears to be more applicable to Windows Server 2008. The calling of the Virtual Disk service must be invoked by something working behind the scenes. I don't see any disruption of activity. I guess I'll just have to chalk it up to another mysterious event log fodder culprit, as long as it doesn't interfere with the performance of my system.

In the event viewer, you can look at things like hardware, IE, etc. events. You might find something there. These are in the Application and Services logs.
