By default, the NetBIOS name resolution mode used by NetBIOS over TCP/IP
is B-node mode. If a WINS server is specified in the TCP/IP configuration,
the default mode is H-node.
In Windows for Workgroup running TCP/IP-32, these default settings can
be modified to change to NetBIOS name resolution mode to B-node, P-node,
M-node, or H-node.
To change the NetBIOS name resolution order:
- Open the SYSTEM.INI file with a text editor.
- In the [NBT] section, add the following entry:
NodeType = 1, 2, 4, or 8
These values specify the mode of NetBIOS name resolution used by NetBIOS
over TCP/IP, where:
1 = b-node
NOTE: This value can also be configured via DHCP Manager on the DHCP
server. Under DHCP Options, select Scope or Global. The default is 1 (b-
node). If no value is specified and a WINS server is specified and its
NodeType is blank, then the default is 8 (h-node). On the Windows for
Workgroups client configure it to use DHCP under Control Panel, Network,
highlight TCP/IP Protocol in the Installed Network Software windows and
select Configure. Enter an X in the Enable Automatic DHCP Configuration
box by clicking on it. Click on OK and reboot the Windows for Workgroup
2 = p-node
4 = m-node
8 = h-node.
- Save your changes and restart Windows.
NOTE: For more details on node type implementation refer to TCP/IP-32
