Description

Directs the Dynamic Host Configuration Protocol (DHCP) client to ignore Media Sense events from the interface.

Media Sense provides a mechanism for network adapters to notify the protocol stack when network media is connected or disconnected. The protocol stack can then update its network configuration parameters. Media Sense is especially useful on portable computers, which are commonly disconnected from one network and connected to a different one.

Media Sense events direct the DHCP client to take an action, such as attempting to obtain a lease when media is connected or invalidating the interface and routes when media is disconnected.

Value

Meaning

0

Enables Media Sense on the DHCP client.

1

Disables Media Sense on the DHCP client.

Note Image Note

Because 10b2 or coaxial (RG-58) Ethernet cable is not connection-based media, Media Sense does not detect connection and disconnection events on this type of network cable.

NetBIOS Enhanced User Interface (NetBEUI) and Internetwork Packet Exchange (IPX) do not recognize Media Sense events.

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
