HKLM\SYSTEM\CurrentControlSet\Services\
The RemoteAccess subkey stores configuration data for Routing and Remote Access.
Several other subkeys, such as RasMan, RasAuto, and RasAcd, also store entries for secondary services that support dial-in connections. The RemoteAccess subkey stores data that applies to the entire service.
Some entries in this subkey can be changed by using the Routing and Remote Access Manager. For details, see the description of each entry.
