Which is the default TCP connect timeout in Windows?

Which is the default TCP connect timeout in Windows? There is a registry key to configure it or it's set dynamically?

From serverfault Renan Vinícius Mozone

• In Windows the value is dynamic for established conections, though the default for initial connections is 72 seconds. The Registry settings are defined in this article:

  http://technet.microsoft.com/en-us/library/cc739819(WS.10).aspx

  HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services: \Tcpip \Parameters

  TcpInitialRTT: Defines what the initial time-out settings are for new connections. This number in seconds is doubled each time it retransmits before timing a connection out. Defaults to 3.

  TcpMaxConnectRetransmissions: Defines the number of retransmissions before timing a connection out. Defaults to 5.
