All you need is a blank disk and a little patience.
A 3.5" MS-DOS 6.22 boot disk that lets you boot a computer and access shared files
across a TCP/IP network is a useful administrative tool. A TCP/IP boot disk is
handy when you’re using imaging software to roll out a standard client image
across the network, running an unattended installation of Windows NT 4.0, or troubleshooting
a machine that has a FAT partition. The main problem with a TCP/IP boot disk is fitting onto one
disk all the files that you need to access a share across a TCP/IP-based network.
Few administrators have access to a machine that they can use to directly format an
MS-DOS TCP/IP boot disk. However, you can use the following procedure to make such a disk.
You need a blank 1.44 MB 3.5" disk, an NT Server 4.0 CD-ROM, MS-DOS network adapter drivers,
and a Windows workstation. You need to create a separate boot disk for every different type
of network adapter you use.
Step 1
Insert a blank, formatted 3.5" disk into the workstation’s drive A.
Step 2
Insert the NT Server 4.0 CD-ROM into the workstation’s CD-ROM drive (This description uses drive E).
Step 3
Run E:\support\hqtool\makedisk.bat to create an NT 4.0 hardware query disk,
which works as an MS-DOS boot disk that you can customize.
Step 4
After makedisk.bat has finished running, go to the 3.5" disk. Remove hardware query components
that makedisk.bat has placed on the disk (i.e., A:\zipfile.exe, A:\setramd.bat,
A:\dos\findramd.exe, and A:\dos\ramdrive.sys). The boot disk doesn’t need the hardware
query components, and they consume valuable disk space that you need for the TCP/IP
networking components.
Step 5
To ensure that A:\autoexec.bat doesn’t reference any files that you removed in Step 4,
edit A:\autoexec.bat to contain only:
@echo off
prompt $p$g
SET PATH=A:\DOS
Step 6
To prevent errors when config.sys attempts to reference the hardware query components
that you deleted, edit A:\config.sys to contain only:
DEVICE=A:\DOS\HIMEM.SYS
DEVICE=A:\DOS\EMM386.EXE FRAME=NONE
DOS=HIGH,UMB
FILES=30
BUFFERS=20
LASTDRIVE=Z
STACKS=9,256
SHELL=A:\COMMAND.COM A:\ /E:512 /P
This step completes the creation of the MS-DOS boot disk.
Step 7
Copy the E:\clients\msclient\netsetup folder and its contents to
a FAT partition on your local system (this example description uses drive C) that you can
access when you boot from your new boot disk. The system will use the Netsetup files
to install the TCP/IP networking component to the disk.
Step 8
Create a folder on drive C and name it NIC_Driver.
Copy your network adapter’s MS-DOS\Windows for Workgroups (WFW) 3.11 drivers into the
NIC_Driver folder. (You can find the drivers on the CD-ROM or disk that came with the
adapter or download the drivers from the adapter manufacturer’s Web site).
You need at least the oemsetup.inf install file and
nic_card.dos driver file.
If your adapter doesn’t have an oemsetup.inf file, copy the drivers that are available,
then use the workaround described for this situation when you reach Step 12.
Step 9
Use your newly created boot disk to reboot your machine.
Step 10
Type C:\netsetup\setup.exe at the command prompt,
then press Enter to start the setup program for Microsoft Network Client 3.0 for MS-DOS.
Press Enter again to set up the Network Client software on your boot disk.
Step 11
Select C:\net in the Network Client directory and press Enter.
The network setup program creates a C:\net folder and places all the necessary binaries
and configuration files into that folder. You specify the local hard disk,
not the boot disk, as the file destination because the Network Client setup program copies
more than the essential files, and those files take up more space than is available on the boot disk.
In later steps, you’ll remove superfluous files from the C:\net folder and place
the streamlined C:\net folder on your boot disk.
Step 12
A screen that lists network adapters appears. From the list, select the network
adapter that your system is using. If your adapter doesn’t appear on the list, select
Network adapter not shown on list below and press Enter.
On the next screen that appears, enter the path to the NIC_Driver folder that you created
in Step 8 (due to the 8.3 naming format of MS-DOS, a folder named NIC_DRIVER will
be accessible under MS-DOS as NIC_DI~1). The next screen that appears
displays a list of network adapters that your drivers support.
Select your adapter, and when the next screen prompts you, press Enter to
select the Setup for best performance option.
This option configures the network drivers to use more memory for network buffers.
If you found in Step 8 that your network adapter doesn’t include an oemsetup.inf
file, you can select any network adapter from the list, manually copy the nic_card.dos
driver for your network adapter into the A:\net folder, and copy into
A:\net\protocol.ini the entries in the sample protocol.ini
file that comes with your nic_card.dos driver.
You also need to change the netcard, lana0, and bindings
entries in A:\net\protocol.ini to point to the new driver section.
This listing contains a sample protocol.ini file.
After you adjust the protocol.ini file, edit the netcard entry in
A:\net\system.ini to point to the new
nic_card.dos driver.
Here is an example of the
[network drivers] section of a system.ini file.
Step 13
After you select your adapter, the setup program asks you for a username.
Type the domain account that you’ll use to connect to the remote share
(this description uses the username: Administrator). Press Enter.
Step 14
The next screen that appears, the setup menu, lets you change names, setup options, and network
configuration. Select the Change Names option, and on the resulting screen (as pictured below),
set Change Computer Name to a unique name and set Change Domain Name to the domain in which the
Administrator user account resides.
Press Enter, and the program returns you to the setup menu.
Select Change Setup Options, and on the resulting screen,
set Change Logon Validation to Logon to Domain, as shown here.

Press Enter to return to the setup menu, then select Change Network Configuration. The next screen,

shows two boxes; you can press Tab to toggle between the boxes. By default,
the NWLink IPX protocol is bound to the network adapter. To add the TCP/IP protocol,
shift to the lower box, select Add Protocol, and press Enter. A list of protocols appears.
From the list, select Microsoft TCP/IP and press Enter.
You return to the previous screen.
To remove the NWLink IPX protocol, toggle to the upper box and choose NWLink IPX Compatible Transport.
Then, move to the lower box, select Remove, and press Enter. The resulting window will look
similar to the screen sampled above.
If your network doesn’t use DHCP to configure clients, you need to change the TCP/IP settings
to give your network adapter a static IP address. Select Microsoft TCP/IP in the upper box,
then toggle to the lower box and select Change Settings. Press Enter.
The resulting screen lets you specify an IP address, subnet mask, and default gateway.
To disable the DHCP client, you also need to set Disable Automatic Configuration to 1.
Step 15
Press Enter as many times as necessary to reach the setup menu.
On the setup menu, select The listed options are correct,
and press Enter.
When the setup program prompts you for an OEM driver disk, press Enter again.
Then, press F3 to finish setup without rebooting. Eject the boot disk, and reboot
to your main OS.
Step 16
To fit the C:\net folder and its contents onto the boot disk, you need to remove all
nonessential files. Open the C:\net folder and delete:
C:\net\setup.exe
C:\net\sockets.exe
C:\net\nwlink.exe
C:\net\expand.exe
C:\net\ping.exe
C:\net\ipconfig.exe
C:\net\addname.exe
C:\net\win_sock.dll
C:\net\winsock.dll
C:\net\wsockets.dll
C:\net\rascopy.bat
C:\net\vbapi.386
C:\net\vsockets.386
C:\net\readme.txt
C:\net\*.inf
Step 17
Copy the directory C:\net to your boot disk, and use a text editor to
replace C:\net with A:\net in the autoexec.bat, config.sys, and system.ini configuration files on the boot disk.
For example, change C:\net\autoexec.bat to A:\net\autoexec.bat.
Step 18
Open the A:\net\system.ini file, and find the [network] section.
Within that section, replace the workgroup=WORKGROUP line with
passwordcaching=no.
The boot disk doesn’t require the workgroup line, and setting passwordcaching to "no"
ensures that a file on your boot disk doesn’t cache your user account password;
such a cache might create a security problem in some organizations.
After you complete these 18 steps, you have a TCP/IP boot disk with about 200KB
of space to spare. I’ve used this method successfully with Ethernet and Token-Ring LAN adapters.
If you need boot disks for more than one computer, use the diskcopy.exe command to
make copies of your new boot disk. To avoid an identity crisis on your network,
you need to change the computername entry in A:\net\system.ini to make each disk unique.
If you specified a fixed IP address instead of using DHCP, you need to change the IP
address in the TCP/IP section of the A:\net\protocol.ini file to a unique address on each disk you copy.
Your TCP/IP boot disk will let you boot clients to your TCP/IP network and use
the Net Use command to map network drives.
