Disable: 'MSS: (TcpMaxDataRetransmissions) How many times unacknowledged data is retransmitted (3 recommended, 5 is default)' for TcpMaxDataRetransmissions
MSS: (TcpMaxDataRetransmissions) How many times unacknowledged data is retransmitted (3 recommended, 5 is default)
Counter Measure:
Configure the MSS: (TcpMaxDataRetransmissions) How many times unacknowledged data is retransmitted (3 recommended, 5 is default) entry to a value of 3. The possible values for this registry entry are:
? 0 to 0xFFFFFFFF. The default configuration is 5.
In the SCE UI, this setting can be adjusted using a text entry box:
? A user-defined number
? Not Defined
Potential Impact:
TCP starts a retransmission timer when each outbound segment is passed to the IP. If no acknowledgment is received for the data in a given segment before the timer expires, then the segment is retransmitted up to three times.
Parameter:
Technical Mechanism:
(1) GPO: Computer Configuration\Administrative Templates\MSS (Legacy)\MSS: (TcpMaxDataRetransmissions) How many times unacknowledged data is retransmitted (3 recommended, 5 is default)
(2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\TcpMaxDataRetransmissions
