Default IP time to live

Can someone tell me where in the registry I can locate
the default IP time to live and what that would be in
minutes? We are having some issues with an app on this
server that loses its connection with an UNIX box. This
app does not automatically reconnect. So the question
came up on how long the time outs are on both W2K and
UNIX that would trigger it to disconnect.

Thanks...
 
tcp/ip parameters can be found from
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters".

WindowsXP recognizes this optional parameters that are not there by default.
You must add them manually. I believe also Windows 2000 has most of them. I
don't know how these value names are used and which valeus there can be
used. So be careful when you add any of them. Here most values are zeros,
but actual values most likely shouldn't be.
