Control Keep Alive Parameters (Windows NT/2000/XP)
Category: Home > Network > Protocols > TCP-IP
These settings control how Windows manages connection keep alive transmissions. Including the timeout before keepalives are sent and the interval between keepalive transmissions.
Open your registry and find the key below.
Create new DWORD value named "KeepAliveTime" and set it to equal the number of milliseconds to wait before sending keep alive packets (the default is 2 hours - 7,200,000 milliseconds).
Also create a new DWORD value called "KeepAliveInterval" and set it to equal the time in milliseconds between retransmissions of keepalives, once the KeepAliveTime has expired (the default is 1 second - 1000 milliseconds).
Restart Windows for the change to take effect.
