The four TCP/IP node types are defined by number in Windows:
1 - bnode (broadcast only)
2 - pnode (WINS only)
4 - mnode (broadcast, then WINS)
8 - hnode (WINS, then broadcast)
The default Windows TCP/IP node types are:
If DHCP=False, and WINS is disabled, then NodeType=1 (bnode)
If DHCP=False, and WINS is manually set, then NodeType=8 (hnode)
If DHCP=True, and DHCP sets WINS, then NodeType=8 (hnode)
If DHCP=True, and WINS is manually set, then NodeType=8 (hnode)
If DHCP=True, and WINS is disabled, then NodeType=1 (bnode)
NOTE: If WINS server options are provided via DHCP then Node Type should be set using DHCP option 46; however, locally defining a WINS server on the client will override these two options, as locally defined WINS servers automatically set your node type to H-Node.
The node type can be manually changed by editing the Windows registry. The location is under the HKEY_LOCAL_MACHINE subtree under the following subkey:
SYSTEM\CURRENTCONTROLSET\SERVICES\VXD\MSTCP\NodeType
The four values listed above (1, 2, 4, 8) are valid values for NodeType.
NOTE: NodeType can be added as a String value under MSTCP if it does not already exist.
