Registry Keys Added by Remote Access Service

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

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.
