Remote Access Service

Users connecting to a RAS services, through a modem, can limited to accessing only that server, or can be access to the entire network. effectively, this is same as the local connection to the network, except that any type of data transfer runs significantly slower. you will need to select connection option appropriate to your access requirements available support, and budgetary constraints.

In the current business environment, organizations are under pressure to reduce costs, increase efficiency, and maximize performance from the existing infrastructure. The growth of the Internet, together with new global business opportunities, makes it imperative that organizations provide secure 24x7 network access to employees and locations around the world.

Introduction of Remote Access Service:

In most networks clients are connected directly to the network. In some cases, however remote connection are needed for your users. Microsoft provides Remote Access Services to set and configure client access.

The RAS API is designed for use by C/C++ programmers. Microsoft® Visual Basic® programmers may also find the API useful. Programmers should be familiar with networking concepts.

Some of the functions in the RAS API are supported only on network servers and other functions are supported only on network clients. For more specific information about which operating systems support a particular function.

RAS Common Dialog Boxes :

Windows provides a set of functions that display the RAS dialog boxes provided by the system. These functions make it easy for applications to display a familiar user interface so that users can perform RAS tasks. For example, users can establish and monitor connections, or work with phone-book entries. Windows 95 does not currently support these functions.

The Ras Phonebook Dlg function displays the main Dial-Up Networking dialog box. From this dialog box, the user can dial, edit, or delete a selected phone-book entry, create a new phone-book entry, or specify user preferences. The Ras Phonebook Dlg function uses the RASPBDLG structure to specify additional input and output parameters. For example, you can set members of the structure to control the position of the dialog box on the screen. You can use the RASPBDLG structure to specify a RasPBDlgFunc callback function that receives notifications of user activity while the dialog box is open. For example, RAS calls your RasPBDlgFunc function if the user dials, edits, creates, or deletes a phone-book entry.

You can use the RasDialDlg function to start a RAS connection operation without displaying the main Dial-Up Networking dialog box.

With RasDialDlg, you specify a phone number or phone-book entry to call. The function displays a stream of dialog boxes that indicate the state of the connection operation. The RasDialDlg function uses a RASDIALDLG structure to specify additional input and output parameters, such as position of the dialog box and the phone-book subentry to call.
