IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

This article describes the TCP/IP node-type settings in Windows.

MORE INFORMATION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

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.

For more information, please see the Windows 95 or the Windows 98 Resource Kit.
