How to shorten timeout for connection to a non-existing IP

This command

 

C:\>telnet 123.45.67.89 1521

Connecting To 123.45.67.89...Could not open connection to the host, on

port 1521: Connect failed

 

comes back with Connect failed error in about 20 or 21 seconds. What

can be done to shorten this time? I tried these registry settings at

HKLM\System\CurrentControlSet\Services\Tcpip\Parameters:

 

KeepAliveTime 120000

TcpTimedWaitDelay 120000

TcpWindowSize 64512

TCPMaxRetransmissions 1

 

The telnet still hangs for about 20 seconds. What am I missing?

Thanks.
