SUMMARY
This document describes the default NetBIOS Node type for Windows if it is not specifically designated by a DHCP Server.
MORE INFORMATION

Windows 2000 and Windows NT

NodeType
Key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters

Value Type: REG_DWORD - Number
Valid Range: 1,2,4,8 (b-node, p-node, m-node, h-node)
Default: 1 or 8 based on the WINS server configuration
Description: This parameter determines what methods NetBT will use toregister and resolve names. A b-node system uses broadcasts. A p-nodesystem uses only point-to-point name queries to a name server (WINS). An m-node system broadcasts first, then queries the name server. An h-nodesystem queries the name server first, then broadcasts. Resolution throughLMHOSTS and/or Domain Name Service (DNS), if enabled, will follow thesemethods. If this key is present, it will override the DhcpNodeType key. Ifneither key is present, the system defaults to b-node if there are no WINSservers configured for the client. The system defaults to h-node if thereis at least one WINS server configured.

Windows 95

NodeType
Key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP

Value type: DWORD
Valid range: 1, 2, 4, or 8
Default: 1 (b-node) if no value is specified or no WINS servers areconfigured on the network; 8 (h-node) if WINS servers are specified andNodeType is not otherwise defined in the Registry.
Description: This parameter specifies the mode of NetBIOS name resolutionused by NetBIOS over TCP/IP. 1 = b-node (broadcasts), 2 = p-node (point-to-point name queries to a WINS server), 4 = m-node (broadcast then query nameserver), and 8 = h-node (query name server, then broadcast). If DNS isenabled (which also enabled LMHOSTS in Windows 95), name resolution willalso follow the mode defined by this parameter. This value can also beconfigured using DHCP.
