Perhaps because the root folders are typically already shared as hidden
admin shares (e.g. \\server\c$ )

What is the return code when it fails?

If Convert.ToInt32(outParams.Properties("ReturnValue" ).Value) = 0 Then
MessageBox.Show("Successfully")
Else

MessageBox.Show(Convert.ToInt32(outParams.Properti es("ReturnValue").Value))
End If

Hi yxq,

In a NT environment... NT4, 2000, 2003, XP, the root directories are shared
for administrative purposes as <driveletter>$, etc. You cannot remove, nor
change permissions, on these shares as they are managed by Windows itself.

You can, however, share the drive again as a different name, i.e. C$ points
to C:\ and Drive_C also points to C:\, then you can remove Drive_C, but you
cannot remove the Administrative shares.
