PPTP Registry Settings (Windows CE 5.0)
The registry stores information necessary to configure the system for applications and hardware devices. The registry also contains information that the operating system continually references during operation.
To configure the PPTP implementation, you can set the following optional registry values on the client device.
Note The default registry values vary depending on which Catalog items are included in your OS design. For more information, see Default Registry Settings.
The following table shows the named values for the HKEY_LOCAL_MACHINE\Comm\Pptp1\Parms key.
