oFSO = CREATEOBJECT("Scripting.FileSystemObject")
oFolder = oFSO.GetFolder("C:\")
?oFolder.Size

When I run this code from the Command Window, the .Size grinds away on my HD for about 12 seconds (which is as expected, it's scanning all folders/files) then craps out with

OLE error code 0x800a0046: Unknown COM status code.

I'd like to find out if it's limited to my system or if others get it too.

My environment:
W2K SP2 + all critical updates and security patches - logged in as Administrator
IE6 6.0.2600.0000 with all security patches
VFP7 build 9262 with available patches
