Summary:
The following procedure sets up a Centrum Remote (3Com Access Server) client to communicate on a Windows for Workgroups 3.11 and Novell Netware 3.11 LAN.

Solution:
Some manual editing is involved in this setup.

Make sure that you have a copy of any network utilities (that you use often) on your local hard disk. This is important as any applications that you will be using over the network must first be copied to your PC's memory. Therefore, if you are using something that is 200k in size and your Modem link is 19200 baud it will take approximately 2 minutes to load into memory. One application that you will need on your local hard disk is LOGIN.EXE as this will reduce login time dramatically. Some planning is involved here. If your Netware Login Script has many drives being mapped, and printer ports being redirected, then each of these redirections or mappings require a separate instance of MAP.EXE or CAPTURE.EXE to be loaded into your PC's memory, so for any remote nodes try to keep the login scripts to a bare minimum.

There are basically 5 steps in this procedure:

1. Back up all associated disks and data.

2. Setup the Remote Node so that you can Login using just DOS.

3. Setup the Windows Network to use the network driver IPXODI Support (Ethernet)

4. Edit Network Protocol files

5. Edit Config.sys and AUTOEXEC.BAT

1. Use the supplied Client Driver Disk.

2. Make a backup copy of this disk. (You will need it later.)

3. Copy the contents of the disk into a subdirectory on your hard disk. This will make it easier to change settings later (also you can never have too many copies of vital data).

4. Change to that sub directory.

5. Run the Centrum Remote Client Setup. CRSETUP.EXE

6. Install the Software onto your PC.

7. Fill out the appropriate forms. (If you are not sure about something then read your manuals thoroughly. All these fields are explained in the manuals.)

8. When you press OK, you will be prompted for a Network Type. Select Novell 2.xx/3.xx. This will install the ODI driver you need (called PKMLID.COM).

9. Copy the following files from your old network driver directory (or from another PC) into the directory where your Centrum Remote client software was installed: LSL.COM, IPXODI.COM, NETX.EXE, NET.CFG

9. Edit your AUTOEXEC.BAT file: Replace your previous network drivers (where they were being loaded), with the contents of the CRLOGIN.BAT file (in directory containing the Centrum Remote software). This would typically be:

OLD AUTOEXEC.BAT

@echo off
Prompt $p$g
Path c:\;c:\dos;c:\windows
c:\windows\smartdrv /X 1024 512
cd\net
lsl
ne2000
ipxodi
netx
cd\
f:
login
etc.......

NEW AUTOEXEC.BAT (example only - yours may be different)

rem C:\WINDOWS\net start
@ECHO OFF
path c:\;c:\dos
prompt $p$g
C:\WINDOWS\SMARTDRV.EXE /X
echo continuing will load Centrum Network drivers
pause
goto centrum
cd\boot
lsl
ne2000
ipxodi
C:\WINDOWS\odihlp.exe
netx
f:
login
c:
goto rest
:centrum
cd\cremote
CRAGENT
if errorlevel 1 goto crexit
DIAL
if errorlevel 1 goto crexit
LSL
PKMLID
IPXODI
c:\windows\odihlp.exe
NETX
pause
login
:crexit
:rest
cd\
PATH=C:\CREMOTE;C:\WINDOWS;C:\;C:\DOS;C:\CITECT\BIN;C:\EXCEL;C:\MOUSE;%PATH%
SET TEMP=C:\WINDOWS\TEMP

10. Edit your Net.cfg file for logging on to Novell. This file should always be placed in the same directory where you run your network drivers (LSL,IPXODI etc). Most likely the directory C:\CREMOTE. This Net.cfg file was previously used to load a NE2000 card.

NET.CFG

LINK DRIVER PKMLID
Frame Ethernet_802.3
INT 3
Port 2F8
Protocol IPX 0 Ethernet_802.3
Frame Ethernet_II
Frame Ethernet_802.2
Frame Ethernet_SNAP
LINK DRIVER NE2000
FRAME ETHERNET_802.3
INT 15
FRAME ETHERNET_802.2
FRAME ETHERNET_II
FRAME ETHERNET_SNAP
PROTOCOL IPX 0 ETHERNET_802.3
show dots=on
all servers=on
file handles=154
ipx retry count=4

11. Edit your Protocol.ini file. This will be in your Windows directory. (Most likely C:\WINDOWS.)

[network.setup]
version=0x3110
netcard=ms$odimac,1,MS$ODIMAC,4
transport=ms$nwlink,NWLINK
transport=ms$netbeui,NETBEUI
lana0=ms$odimac,1,ms$nwlink
lana1=ms$odimac,1,ms$netbeui
[net.cfg]
PATH=C:\CREMOTE\NET.CFG
[MS$ODIMAC]
[Link Driver PKMLID]
[NWLINK]
BINDINGS=PKMLID
[NETBEUI]
BINDINGS=PKMLID
LANABASE=0
SESSIONS=10
NCBS=12

12. Save everything and you should now be ready to log on to your Novell File server, and run Windows for Workgroups 3.11. It will be slower than a real LAN because your connection has gone from a band width of 10 Megabytes/Sec to whatever your modem will support, probably 19200 or 9600 baud.
