The Media Sensing feature in Windows 2000, Windows XP and later is used to detect whether the network media are in a link state. With Media Sense feature,  Windows senses a link state as UP or DOWN based on the link availability. When Windows detects a “down” state, it removes the bound protocols from that adapter until it is detected as “up” again.

Media Sensing feature is enabled by default in Windows except Windows Server 2003. However, in instances where you do not want Windows to sense link status (very unlikely) in which case, you can disable the Media Sensing feature from Windows Registry.

This applies to Windows Server 2008, Windows Vista, Windows XP, Windows Server 2003 (if enabled) and Windows 2000.

The following procedure to edit the Windows Registry should help you disable the Media Sensing feature.

1. Click Start -  Search and type “regedit” [In Windows XP/2003, Click Start - RUN and type "regedit"]. This launches the WIndows Registry.

2.  In the registry, navigate to the following registry key



3. In the right pane, right-click and select New – DWORD (32-bit value) and set its name as “DisableDHCPMediaSense” and set its value as “1″. Setting “1″ will disable Media Sensing feature. Should you like to enable Media Sensing at a later time, set it “0″ or simply delete the this key.
