Protocols Available
Network Services Installed


There are numerous ways to install a Windows NT 4.0 Workstation as well as several options to choose from and configure when installing the network adapter. This document contains the instructions on installing and configuring a Racore adapter as part of an original NT 4.0 Workstation installation or when adding an adapter to an existing system. The network section can be added during the original installation or after the workstation has been installed with little difference in the procedure. Due to the many installation options available, this is not a step-by-step guide. The intention of this document is to aid you with the network installation section. This document covers these Racore adapters: M8113, 8114, 8115, 8116, 8117, 8118, 8119, 8134, 8154, 8157.


Before installingWindowNT it is best to have the network adapter installed and tested for functionality using Racore's diagnostics utility, rcpdiags.exe (PCI , PCMCIA Token Ring adapters)or tr16diags.exe (ISA + MCA Token Ring adapters).

Racore Computer Products provides the drivers required by the adapter. Racore Token-Ring Adapter drivers for Windows NT 4.0 include: rcptrnds.sys(PCI, PCMCIA), rtr16nds.sys (ISA+ MCA): The rcptrnds.sys driver works with the 8134, 8154, and 8158 Token Ring adapters. The rtr16nds.sys driver works with the M8115-8119 adapters. These files and related files can be found on the Racore WEB Site.

Additional files related to the rcptrnds.sys driver are:


These files are located in the same directory as the rcptrnds.sys driver on the distribution disk and web site disk image. During the installation the rcptrnds.sys file is copied to the ..\system32\drivers subdirectory. The rcptrnds.dll and the rcptrnds.hlp files are copied to the \system32 subdirectory.

Oemsetup.inf: This file is the first file Windows utilizes when installing the driver. This file contains information on the driver settings and installation parameters.

Rcptrnds.dll: This file is used any time the adapter is configured or reconfigured.

Rcptrnds.doc: This file contains information on adapter configuration settings. A copy of this file is included later in this document.

Rcptrnds.hlp: This fileWindows help file that addresses PCI and PCMCIA adapter installations in Windows NT and Windows 95.

NOTE: The rtr16nds driver's associated files, RTR16NDS.DLL, and OEMSETUP.INF (ISA + MCA adapter) act the same. DISK.ID is required for OEMSETUP.INF v4.34 and earlier.

Hardware Requirements:

Intel 80486/33 or higher CPU. Anything less than a Pentium is very taxing on the processor.

120 MB disk space.

12 MB RAM, 16 MB recommended by Microsoft. I have found that 32 megs will lessen the swap to hard drive that can still occur with 16 megs.

VGA monitor.

CD-ROM to access the Windows NT CD. The entire installation directory \i386 can be copied to the hard disk or on a network file server, but access to a network server is not practical if you are attempting to install the OS or even just the networking components for the first time from a server, i.e. no network access - no access to the files. Keep this in mind when reinstalling an adapter - many related networking files are removed and will require reinstallation too, not just the driver file. Unlike Windows95, NT does not remove the other networking components when the adapter driver is removed.


We begin the installation here: Windows NT Setup, step #2

1st Network Wizard Window
Network Access:
"Windows NT needs to know how this computer should participate on a network."

Select "This computer will participate on a network." (selected by default). Additionally, select "Wired to the network:---Your computer is connected to the network by an ISDN Adapter or Network Adapter" (Also selected by default).

2nd Window
Adapter Selection:
Do not have setup start searching for a network adapter, instead manually select one from a list by clicking "select from list." Use the "Have Disk" option and give it the path to the driver. If using the Racore Distribution diskette or disk image downloaded from the Racore web site, the path is a:\windows.nt . Once selected, The "Racore Preferred Token-Ring NDIS Driver" will be highlighted in the "Select OEM Option" screen.

3rd Window
Select the networking protocols that are used on your network. Refer to the section "protocols available to Windows NT 4.0 Workstation" later in this document for a description of the protocols. Options include:

TCP/IP (selected by default)

NWLink IPX/SPX Compatible Transport

NetBEUI Protocol

*4th Window
*Does not appear during a new installation of NT, it is only seen upon installation/reinstallation of an entire network section. These services are listed by default during an original(new) installation.

"Listed below are the services that will be installed by the system"

Network Services: (see network services later in the document for more information on these and other services available to NT).

RCP Configuration

NetBIOS Interface



5th Window
Installation of network components:
"Windows NT is now ready to install networking components that you selected and others required by the system."

The next few screens will vary depending on what adapter you are installing and what protocols you have selected. If you do not deselect TCP/IP you will be prompted for TCP/IP protocol network numbers and related DHCP information.


If an ISA or PCMCIA card is being installed, a Bus Location is requested. Select the bus type and bus number where the Racore adapter is located.

The options (system dependent) may include:
Type (bus type):
PNP BIOS (ISA Plug and Play)

0,1 (system dependent)

If you are installing a PCI adapter the following will appear:
"PCI Adapter found - Install PCI adapter in Bus X Device XX?"

If a PCI adapter is not found, the Bus location window will appear.

RCPTRNDS Token Ring Adapter Card Setup Window

Adapter Card Setup Window

5. Adapter card configuration: The default settings for the adapter appear now in the "RCPTRNDS Token Ring Adapter Card Setup" window. The autodetect setting will work with most computers for all but the Port Address. The cards ports address must be configured for ISA adapters. The Port address for PCI adapters must be set to "PCI."

The following table describes the available options.This information is also available in the readme file, rcptrnds.doc


Configuration Information


Port Address

A port address must be selected. PCI adapters select "PCI" PCMCIA adapters must assign a non conflicting port


IRQ Level

Set to "Autodetect" PCMCIA adapters must have a value selected


DMA Channel

Set to "Autodetect" except PCMCIA adapters which must be set to pseudo DMA channel


Memory Address

Set to "autodetect" execpt PCMCIA adapters which must select a non-conflicting memory address.


Network Address

If you wish to use a locally administered network address, enter a 12 digit hexadecimal address.


Speed setting

set to network speed.

16 mb/s

Max Frame Size

Set desired frame size (1024-8192). Changing this value will affect performance.


Transmit Lists

Set desired of transmit buffers. Changing this value will affect performance.


Receive Lists

Set desired number of receive buffers. Changing this option must be selected.


Use Config Register

With the exception of PCMCIA adapters, this option must be selected.


Promiscuous Mode

Select this option if you wish to allow your adapter to copy all frames (see all activity on the network). Some software, such as network analyzers, may require this.

not selected

Wait State

PCMCIA adapters only. Set this option to lengthen I/O read and write events. This may increase hardware compatibitity on certain PCMCIA PC's, but will decrease network performance.

not selected

NOTE: For the M8113, 8114, 8116, 8118 you must insert a Network address. The 8113, 8114 must have the rtr16llc.cod file in the WINNT\SYSTEM32 subdirectory and the card must be set to RAM mode in the system setup (see Racore Adapters: additional notes)..

*TCP/IP Configuration Window

*See the section on Installing TCP/IP for information on configuring TCP/IP.

*Bindings Window -no configuration necessary

*Only appears when reinstalling the network section. "you may use this page to disable network bindings or arrange the order in which this computer binds information on the network."

Show bindings for ALL SERVICES:(other options incluse all protocols, all adapters)

NetBIOS Interface



Installation Window -no configuration necessary

"Windows NT is now ready to start the network so that you can complete the installation of networking."

*Network settings change windows -no configuration necessary

*Only appears when the network is removed and reinstalled.

Workgroup Window

"Select whether your computer will be participating in a workgroup or a domain and enter the name of the workgroup." Enter the workgroup or domain names here. There must be a domain server on the network and you must have certain domain rights before you can join a Windows domain. This Domain is not the same as the DNS Domain Name Service domain. A Windows Domain is a group of computers identified by a domain name for security and administrative purposes.

The last network installation window

"Networking has been installed on the computer."

You will now be prompted to restart the computer for settings to take effect.

This ends the network installation.

Racore Adapters: Additional Notes

PCMCIA cards:

Select the PCMCIA bus location type when the Bus Location screen appears. The default settings that appear in the card setup window will work in most cases. If the card does not function, run diagnostics on the adapter and verify that the settings listed in diags are those used in NT, if not change the settings in NT.

M8113, 8114, 8115 Token-Ring cards:

Add the RTR16LLC.COD file found in the diags subdirectory of the Racore disk to the \system32\drivers subdirectory (it is important that it is located in the same directory as the driver rcptrnds.sys). Set the card to RAM mode, switch 11 open or off on the 8113 adapter, switch 5 off on the 8115 adapter.

Installing Netware Access

To Access NetWare 4 networks:

1. Create an Admin user on the NT workstation (facilitates access to Netware 4 servers as an administrator) and give it administrator group rights.

2. Give Admin the same password as the Admin user has on the NetWare 4 network.

3. Add the client service for NetWare service (CSNW) to the network (located in the control panel).

CSNW provides file and print services. Installing CSNW will ad NWlink protocol, Microsoft's version of Novell's IPX/SPX protocol, the default protocol used on NetWare servers.
IPX is faster than TCP/IP and provides an easy connection to Netware Servers or workstations. One disadvantage is that it is not SNMP compliant.
Once the computer is rebooted you will be prompted for NetWare network login information.

4. Select "NetWare Logon" and fill in the default tree and context if you are logging on to NDS. Choose to run login script if desired.

Installing TCP/IP

Step one. DHCP Configuration: The first TCP/IP window asks:

" If there is a DHCP server on your network, TCP/IP can be configured to dynamically provide an IP address. If you are not sure, ask your system administrator. Do you wish to use DHCP?"

DHCP or Dynamic Host Configuration Protocol will assign an IP address to the workstation if there is a DHCP server on your network. DHCP is a service available on an NT 4 Server. This way all the administration of IP addressing is under the control of the DHCP on the server, enabling the IP address to be used only when needed and making more use of IP addresses if you have a limited number. If you do not use DHCP the host must be configured manually as follows.

Step two: Configuring Microsoft TCP/IP properties.

The Adapter (1) Racore Preferred Token Ring Adapter options:

Microsoft TCP/IP properties

Obtain an IP address from a DHCP server (or)

Specify an IP address

IP Address: Requires a specific address provided by INIC if you access the internet directly.
Subnet Mask: (default for class c network) The subnet mask is required if your network is divided into subnets.
Default gateway: Input the IP address of the server that connects your LAN to the internet or ISP usually by way of a router.

Advanced: Advanced settings window allows the addition of more IP addresses, subnetmasks, gateways.

Enable PPTP Filtering

PPTP or Point to Point Tunneling Protocol is part of Microsoft's Virtual Private Networking. VNP creates an additional level of security for a Corporate LAN when accessing the LAN via the Internet. The additional protocol acts as a barrier to normal internet traffic that can flow into a LAN.

Enable security
A window that enables selected permissions for TCP Port, UDP Ports, IP Protocols.


DNW window

Domain Name System (DNS) is a database containing a hierarchical naming system providing name to IP addressing. Configuring DNS information is required if you wish to use domain names to contact remote systems.

Host Name: By default, the host name is the name used for this computer on the network that was assigned earlier. The host name does not have to be the same as the computer name. Some characters used in computer names cannot be used for host names. Example: The underscore character "_" cannot be used in a host name.

Domain: The domain name is your organizations name as identified on the Internet. Example:

Domain Service Search Order: List the order of priority for DNS servers that will respond to DNS resolutions.

Domain Suffix search order: The suffix is added to a short host name to make a fully qualified domain name from a short name. List the order here.



Windows Internet Name Service (WINS) resolves names to IP addresses in a similar manner to DNS. The difference being that WINS can resolve names that do not follow the hierarchical structure required by a DNS server. DNS requires a static configuration of IP addresses. WINS resolves names dynamically.

Primary WINS Server: Input the location of the main WINS server to access for WINS resolution.
Secondary WINS Server: Input the location of the second WINS server to access for WINS resolution, incase the primary in unavailable.
Enable DNS for Windows Resolution: Check this box if you wish to use Domain Name Service to lookup names. You must enable DNS on each computer that uses LMHOSTS for name resolution.


LMHOSTS are basically files the contain mappings of computer names to IP addresses. Each host must have a copy of the file which must be updated whenever a new name is added to the network.

Enable LMHOSTS lookups (selected by default): Use the LMHOSTS file for name to IP address resolution.
Import LMHOSTS: Specify the location of the LMHOSTS file.

scope ID: The scope id isolates communication to workstations having the same scope ID.


Routing turns on static routing which is used with 2 network cards performing routing functions. It does not support RIP.


Protocols Available to Windows NT 4.0 Workstation

  • TCP/IP

  • NWLink IPX/SPX Compatable Transport

  • NetBEUI Protocol

  • DLC

TCP/IP: Transmission Control Protocol/Internet Protocol, is the default protocol used in Windows NT. TCP/IP is a protocol "suite" that not only connects computers, but networks as well. It is the only protocol that can give you direct access to the internet. It supports SNMP, DHCP, WINS, PPP, PPTP. Its installation is complex. It is the slowest of the available protocols.

NetBEUI: NetBIOS Extended User Interface, uses the NBF transport protocol (IBM).It is a small network protocol. Non-routable, fast, and easy to install. It was the default protocol for Windows in earier version of Windows.

NWLink: Microsoft's implementation of Novell's IPX/SPX protocol stack is used to access Netware networks. NWLink is the Networking component, and IPX is the protocol.

DLC: Data Link Control, is used to access IBM mainframes using terminal emulation programs. It is not an option when installing the network, but can be added in the protocol section later. TCP/IP can be used to connect to mainframes therefore eliminating the need for DLC. DLC is not routeable.

Other Protocol available but not installed by default:

AppleTalk Protocol: AppleTalk protocols are used by Macintosh computers on an AppleTalk network.

PPTP: Point-to Point Tunneling Protocol provides a secure access over the internet to corporate LANS. If you add this protocol you automatically get RAS installed.

Streams Environment: Streams is a UNIX platform driver environment. Enabling streams allows the use of UNIX driver to function on (port to) Windows NT.

Network Services

The following service are available during network installation. Other services can be added later from the services window of the network control panel icon.

  • RCP Configuration

  • NetBIOS Interface

  • Workstation

  • Server

RPC Configuration: RPC or Remote Procecure Calls is a programming interface: A programming interface supplies client server applications with IPC's or Inter Process Communications. In other words, it provides a language that both the server and client can understand. RPC enables the distribution of application workload to several PC's.

NetBIOS Interface: NetBIOS Interface is a programming interface which provides the ability to browse network resources. The interface runs on top of NetBEUI, NetBIOS over NWLink, and NetBIOS over TCP/IP.

Workstation Service: Workstation Service is a redirector. A redirector "redirects" instructions bound internal to the PC out onto the network. The Workstation service provides connectivity, login, and shared resources.

Server Service: The Server Service is another redirector that provides server type resources by controlling shared resources on this computer.


Other Services include:

Microsoft Peer WEB Services: Adds the Internet Service Manager, WWW Service, Samples, Gopher, FTP, and other web tools.

Microsoft TCP/IP Printing: Enables access to UNIX printers using TCP/IP.

Network Monitor Agent: Informs monitor programs on network activity that occurs related to this workstation.

RAS: Remote Access Service - a dial-up service which enables remote access to a LAN.

RCP support for Banyon: Banyon Vines network RCP support.

SAP Agent: Service Advertising Protocol - Enables broadcast advertising of server type services available on the workstation.

Simple TCP/IP Services: Adds character generator, DAtime, Echo, and Quote of the Day services to TCP/IP.

SNMP Service: Enables SNMP or the remote administration of this workstation by a management Agent.
