SUMMARY
=======

When you install the Remote Access Service [RAS] and/or the Point to Point
Tunneling Protocol [PPTP], several registry keys are added or updated. This
article provides a list of those keys for a reference. This list may be helpful
in a situation where an uninstall or reinstall of the either RAS or PPTP has
failed.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
