Registry Entries for Network Adapter Cards

This section describes specific Registry entries related to network adapter cards and the drivers for network adapters. Windows NT supports network adapter drivers under the NDIS 3.0 specification (Network Device Interface Specification).

The CurrentControlSet\Services subkey for a network driver or adapter card includes the standard entries found in the Services subkeys, with the following default values:

Value entry	Value

ErrorControl	0x1 (normal)
Start	0x3 (load on demand)
Type	0x1 or 0x4 (driver or adapter)

The following sections describe entries in the other areas of the Registry that contain configuration information for network adapter cards and their drivers, including:

NetRules subkeys under HKEY_LOCAL_MACHINE\SOFTWARE for drivers and adapters.
Linkage subkey entries under HKEY_LOCAL_MACHINE\SYSTEM for drivers and adapters, defining information about bindings for the component.
Parameter subkey entries under HKEY_LOCAL_MACHINE\SYSTEM for network card adapters, defining specific information such as the IRQ number, I/O base address, and other details.

The information provided here is chiefly to be used for informational and troubleshooting purposes. The settings for either the NDIS driver or the network adapter card should be changed using the Network icon in Control Panel.
