HKLM\SYSTEM\CurrentControlSet\Control\Class\(Network adapters) {4D36E972-E325-11CE-BFC1-08002BE10318}\WAN Miniport (L2TP) <Device-number (000n)>

Data type Range Default value
REG_DWORD 0x0 - 0xFFFFFFFF milliseconds 0x3E8 (1000 milliseconds = 1 second)

Description

Determines how long the L2TP driver waits for a control message to be acknowledged before retransmitting the message. The value of this entry is used the first time each control messages is sent.

The L2TP driver adjusts this value dynamically depending on the network transmission rate. This entry establishes the maximum waiting time after the first transmission.

Consider increasing this value if the network is very slow and calls are terminated prematurely. However, if this value is too high, system resources can be spent on maintaining circuits for unresponsive peers.
