The files, Ppp.dll, Afd.dll, Tcpstkl.dll, and Cxport.dll, are necessary to start a RAS connection. They are stored in the Windows directory on the Windows CE–based device. When RAS starts, it reads the registry phone-book entries. Registry entries contain RAS entry settings, including the device used to dial, the phone number, and other data.
The client logs onto the remote access server and starts the connection.
In some companies, a dial-up remote access server is provided for remote access to the corporate LAN. On a Handheld PC, connecting to a LAN by way of RAS is similar to connecting to an Internet service provider (ISP). You dial in and log on with a user name and password.
