I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Start MPTS, and configure.
Choose your existing LAN adapter,
and choose to add the NETBIOS-over-TCP/IP protocol.

Sorry for not doing "step-by-step",
but when I enter MPTS, to simulate what you want,
it severs my LAN connections, forcing me to reboot.  :-(

Adding a protocol in MPTS has never been a problem.

There should be more parameters to be configured before getting the TCPBEUI work. Things I am not sure about are:
1. NETBIOS SCOPE definition
2. NODE TYPE to be used "B", "P" or "M"
3. NETBIOS Name Server
4. etc, etc.

So please provide more details on these critical parameters.

1. "DOMAIN " is the domain to which you wish to logon. "MACHINE "is the machine which is on the DOMAIN
2.  Start MPTS and press OK and Configure until to get to the "Adapter and Protocol Configuration" screen.  In the "Current Configuration" section you can see how you are configured.  Your current MPTS will probably look something like this:
      IBM Token-ring Adapter
          0 - TCP/IP
          0 - IBM OS/2 NETBIOS
3.  In the "Protocols" window, select "IBM OS/2 NETBIOS OVER TCP/IP" and press "Add".
4.  Your "Current Configuration" will now look something like this"
      IBM Token-ring Adapter
          0 - TCP/IP
          0 - IBM OS/2 NETBIOS
                    0 - IBM OS/2 NETBIOS OVER TCP/IP
5.  Select the "IBM OS/2 NETBIOS OVER TCP/IP" protocol in the "Current Configuration" section
     and press the "Change Number" button.
6.  Select "1" and press the "Change" button.
7.  Your "Current Configuration" will now look something like this"
      IBM Token-ring Adapter
          0 - TCP/IP
          0 - IBM OS/2 NETBIOS
                    1 - IBM OS/2 NETBIOS OVER TCP/IP
    When you have both IBM OS/2 NETBIOS and also IBM OS/2 NETBIOS OVER TCP/IP protocols
    configured on the same adapter, they must have different logical adapter numbers.
8.  While still in MPTS, highlight the "IBM OS/2 NetBIOS over TCP/IP" protocol and select EDIT.  The
      "NetBIOS over TCP/IP" window should appear.
9.  Select "Driver Parameters" and press the "Configure" button.
10.  The driver parameters window will display, which is a list of fields and values.  
      a)  "NODE TYPE" - For this test, we will use B-Node.  If you do not have an option for this, then you
             need to install an MPTS fixpak.
      b)  Make sure the following fields are blank (unused):
               NetBIOS Name Server address
               Backup NetBIOS Name Server address
               Backup NetBIOS Datagram Distributor address
      c)  Scroll down until you see the line "Maximum number of name-ip address pairs in names file".  
            Make sure this is a non-zero number.  You can put 10 in there for this test.
      d)  Make sure the following fields are blank (unused):
               Enter NetBIOS Domain Scope String
               Enter Local NetBIOSName Scope String
11.  Press the OK button, which then returns you to the NetBIOS over TCP/IP panel.  
12.  Select "Names List" and press "Configure".
13.  In this panel, you will enter information for my system.  Press the "ADD" button.  First enter my
        Domain Name  "DOMAIN"  (in Capital letters) in the "NetBIOS name Prefix" field, and my IP
        address "" in the IP Address field.  Press OK.
14.  Press "ADD" again, and this time enter my NetBIOS machine name MACHINE1 and the same
        IP address "
15.  Press "OK" to complete this, and then "OK" again to get back to the "NetBIOS over TCP/IP" panel.  
        By entering these names and IP address, we have created file RFCNAMES.LST which will be
        placed in the \IBMCOM directory.
16.  Select "Broadcast List" and press "Configure".
17.  Press "ADD" to add an entry to the Broadcast list.
18.  Enter my IP address ( and press "OK".  It is possible that this step is not actually required,
        but we will do it anyway.  This step creates file RFCBCST.LST in the \IBMCOM directory.
19.  Press "OK" again and then "Close" so that you are back at the "Adapter and Protocol Configuration" panel.
20.  Press "OK" to complete the MPTS configuration.
21.  Close all windows and save all changes, allowing MPTS to update CONFIG.SYS.  
22.  The basic TCPBEUI configuration is now done.  We now need to modify the File and Print
         configuration file (IBMLAN.INI).
23.  Edit file \IBMLAN\IBMLAN.INI.  If you do not have this file, then you have not installed the File and
        Print client program yet.  You must have it installed.
24.  Find the "Networks" section of the file.  Normally this is near the top of the file.
25.  There should be a "Net1" line.  The Net1 line will probably refer to NETBEUI$.  
26.  Add a new line below the NET1 line.  This line should look something like this:
         Net2 = TCPBEUI$,1,LM10,109,100,14
        Make sure there is NOT a semicolon at the beginning of the line.  (; is a Comment).
27.  You need to add the "net2" keyword in 2 other sections of this file.  In the "Requester" section,
         find the line that begins with "WRKNETS", and add ",net2" at the end of the line.  
         (It will now be:  WRKNETS = Net1,Net2).
28.  In the "Peer" section, find the line that begins with "SRVNETS", and add ",Net2" at the end of that line.
29.  Save the changes and close the file.
30.  Shutdown and reboot.  If you get any errors during the reboot, please record them          and let me know  what they are.
31.  After rebooting, start the Requester program.  Type "NET START REQ".
32.  Try to logon to my server.  Type the following:
                  Logon /v:domain
        This will bring up the logon panel.

33.Finally, You should have a userid and password for that domain !?!@$

Enjoy !
