If you right click on the icon or the notification when it appears, does it give you any more information?
Does it show the Default location? if not, can you click on the link to open the Default location?
Yes, clicking on the link does open the default location.
The default location on my PC contains only the country. New Zealand.
The Event Viewer entries show that the default location was accessed by Windows programs explorer.exe and sidebar.exe
I would assume that these accesses would be OK so why would the warning popup be necessary.
The event viewer is telling you that some program is accessing from the sidebar, and it naturally has to go through explorer to do it.
The program is localizing the area as NZ.
It does sound to me like it is your weather gadget.
If you would like to modify its notifications see: Notifications - Enable or Disable Message Balloons
