Direct-Cable Connection between Win95 and NT4

One of the best proves, that Direct-Cable connection (DCC) and Dialup-Networking (DUN) are closely related, is the possibility to establish a connection between Windows95 Direct-Cable Connection (DCC) and Windows NT4 Dialup-Networking (DUN)/ Remote Access Server(RAS) ( which is (unluckily) limited to serial communications, NOT allowing the higher throughput of a connection via parallel cable)

NT Setup:

Definition of the "Direct Cable" modem

	In the Modem applet of the NT Control-panel, select to add a new modem (if no modem was previously defined, it will start this dialog directly) Put a Check-mark into: "Don't detect my Modem,...."
	Select now manually from the category ("Manufacturer"): "Standard Modem Types" the "Dial-Up Networking Serial Cable between 2 PC's"
	Select the serial port to be used for the connection
	Once this "modem" is installed, check its properties and make sure, that it is configured for the MAXIMUM speed of 115000.

If you have already a network installed, just add RAS to it (skip the next section).
If you have no network installed:

start the network-icon in the Control-Panel and agree to install a network:

	select to install only the "Remote access to a network" (unless you install at the same time also a network board)
	When you are prompted for a Network adapter, do NOT "Start a Search", but defined to "Select from a List"
	Select from the list the "MS Loopback Adapter": for proper operation, NT RAS requires, that a Network card is configured. if no REAL network card is installed, then you need to install this network card emulator. if there is a REAL network card already installed, then there is no need to install this emulator.
	Once the network-card (a REAL one or the emulator) is selected, continue to the next screen and select your protocol. For use of the Direct Cable Connection, keep it simple and select ONLY NetBEUI (the use of IPX/SPX and/or TCP/IP would require much more setup work and is NOT suggested to use for inexperienced personal)
	The verification, that "Remote Access Service" is selected for installation.
	You are prompted for the NT CD-ROM: make sure, that you point it to the proper directory : to the \I386 directory on your CD-ROM .
	The Network card emulator "MS Loopback Adapter" needs to be configured: just leave it on the default "802.3" and continue.
	The Network Setup activates the RAS Setup, which first prompts you to confirm, that the modem "Dialup-Network serial cable" should be added as RAS device. Accept this and select OK

If you had RAS already previously installed, continue here, make sure, that the
"Dialup-Networking Serial cable" is defined as RAS device:

	Configure the port: Since I like to use it in BOTH directions, I select here: "Dial out and Receive Calls"
	Define the Network parameters: in this setup, using NetBEUI as protocol for both Dialing Out and for working as Server (to receive Calls).
	RAS Setup is done. The reminder, that you need to define in User Manager, whether a user is allowed to connect via RAS.
	You can verify the bindings (click on the '+' to expand the display), it should only show NetBEUI-protocol.
	Define your workgroup-name: Both systems MUST be in the SAME Workgroup, but MUST have DIFFERENT Computer names !
	Network/RAS setup is done ! You are reminded TWICE, that you have to restart your system.

Using NT4 as a DCC-Host:
You need to startup RAS for acting as a host (unless configured in Services),
using from the "Administrative Tools" menu the "Remote Access Admin"
(you need to have NT administrator rights to do this job ! ):

	On starting the DCC Client on Windows95, you are prompted with a User Logon screen: you are connecting to an NT system and have therefore now to comply to the NT security scheme. enter a username and password, which is defined in the User-database of NT.
	The DCC client cannot find folder on the Host and asks you now to define the Host-Name: enter the Computername of the NT-system.
	You are connected: The DCC Client connection allows to "View the Host", but also the Network Neighborhood is operational (since we have a network board, real or emulation, installed in the NT system, a network is running with an acting Browse-Master, providing the Network Neighborhood with the information)
	Since we connect only via a serial cable, we can only expect a throughput of approx. 10 Kbytes/sec.

	On the NT-system, you can check the incoming connection using the "Dialup Networking Monitor"
	If the DCC Client has "File-and-Print Sharing" installed, it will be shown in the Network Neighborhood, allowing to access the data of the Win95 DCC-Client from the NT4 DCC-Host.

Connecting from NT Dialup Networking to a Windows95/98/ME DCC-Host:

start up on the Windows 95/98/ME system DCC to act as Host, then:

	Define in NT "Dialup Networking" a new connection, using the "Dialup-Networking Serial cable" (no phone number is required).
	select the proper protocol (should Be NetBEUI) deactivate the Checkmark on: "Enable PPP LCP extentions"
	since there is no user-security on the Windows 95 system, you can define ANY username. However, watch out for the password: If the DCC Host was configure to allow connections WITHOUT a password, do NOT define any password. If the DCC Host requires a password for a connection, define it here !
	You are connected, as you can verify using the "Dialup Networking Monitor". The Network Neighborhood is available to access the data.

Direct Cable Connection between NT4 systems

Although it is not called Direct-Cable-Connection, it is possible to connect
2 NT4-systems directly via a serial cable (NT4 does NOT support a direct
cable connection using a parallel cable ! ).

The setup-steps are identical with the DCC connection with a Win9x system:
- Definition of the "Direct Cable" modem
- define one NT4-system as Host
- define one NT4-system as Client

	Start up RAS. (it takes a few seconds)
	NT is ready to act as DCC host !
