  5. Select “Connect” in the “Default Authentication Level” list.

  6. Select “Identify” in the “Default Impersonation Level” list.

  7. Click OK, and then click Yes to confirm the selection.

  8. Close Component Services console.

  9. It doesn’t mention this anywhere else, but you have to reboot for it to take effect.
