Notes

To perform this procedure, you must be a member of the Administrators group. As a security best practice, consider using the Run As command rather than logging on with administrative credentials. If you have logged on with administrative credentials, you can also open Routing and Remote Access by clicking Start, clicking Control Panel, double-clicking Administrative Tools, and then double-clicking Routing and Remote Access. For more information, see Default local groups, Default groups, and Using Run as.
This feature is not available on the Itanium-based versions of the Windows operating systems.
