Uninstalling NetBIOS over TCP/IP manually

In case MPTS refuses to uninstall NetBIOS over TCP/IP or crashes, here is a cookbook to do it manually.

  1. You have to edit the file x:\IBMCOM\protocol.ini (where x: is your bootdrive).

1.1. Look for the section [IBMLXCFG]!
Remove the line tcpbeui_nif = tcpbeui.nif.
Leave the remaining lines of the section as they are.

1.2. Look for the section [NETBIOS]
Remove the line ADAPTER1 = tcpbeui$,1. Leave the remaining lines as they are.

1.3. Look for the section [tcpbeui_nif]
Remove the complete section.

1.4. Save protocol.ini.

  1. Edit CONFIG.SYS

2.1. Remove (or put a REM in front of) the line DEVICE=x:\IBMCOM\PROTOCOL\TCPBEUI.OS2.

2.2. Remove (or put a REM in front of) the line RUN=x:\IBMCOM\PROTOCOL\NBTCP.EXE .

2.3. In case you want to remove the complete IBM LAN Requester from CONFIG.SYS also remove the following lines: DEVICE=C:\IBMCOM\PROTOCOL\LANPDD.OS2
DEVICE=C:\IBMCOM\PROTOCOL\LANVDD.OS2
DEVICE=C:\IBMLAN\NETPROG\RDRHELP.200
DEVICE=C:\IBMCOM\PROTOCOL\NETBIOS.OS2
DEVICE=C:\IBMLAN\NETPROG\VNETAPI.OS2

IFS=C:\IBMLAN\NETPROG\NETWKSTA.200 /I:C:\IBMLAN /N

SET NWDBPATH=C:\IBMLAN\NETPROG
SET DLSINI=C:\IBMLAN\NETPROG\NETGUI.INI
SET INIT_FILE_NAMES=netgui
SET INIT_FILE_RANGES=200
SET WPS_COMMUNICATION=YES

RUN=C:\IBMLAN\NETPROG\LSDAEMON.EXE
RUN=C:\IBMLAN\NETPROG\VNRMINIT.EXE

2.3. Save your CONFIG.SYS.

  1. Run LMSync.EXE (only necessary if you did NOT remove the IBM LAN Requester).
  1. Reboot.
