MSS: (KeepAliveTime) How often keep-alive packets are sent in milliseconds
The registry value entry KeepAliveTime was added to the template file in the HKEY_LOCAL_MACHINESystemCurrentControlSetServicesTcpipParameters registry key. The entry appears as MSS: (KeepAliveTime) How often keep-alive packets are sent in milliseconds (300,000 is recommended) in the SCE.
This value controls how often TCP attempts to verify that an idle connection is still intact by sending a keep-alive packet. If the remote computer is still reachable, it acknowledges the keep-alive packet.
Parameter:
[150000 or 2.5 minutes/300000 or 5 minutes/600000 or 10 minutes/1200000 or 20 minutes/2400000 or 40 minutes/3600000 or 1 hour/7200000 or 2 hours]
