Value name: EnableDeadGWDetect Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters Value Type: REG_DWORD Valid Range: 0, 1 (False, True) Default: 1 (True) The following list explains the parameters that you can use with this registry value: • 1: When you set EnableDeadGWDetect to 1, TCP is permitted to perform dead-gateway detection. When dead-gateway detection is enabled, TCP may ask the Internet Protocol (IP) to change to a backup gateway if a number of connections are experiencing difficulty. Backup gateways are defined in the Advanced section of the TCP/IP configuration dialog box in the Network tool in Control Panel. • 0: Microsoft recommends that you set the EnableDeadGWDetect value to 0. If you do not set this value to 0, an attack may force the server to switch gateways and cause it to switch to an unintended gateway.
