TCP/IP Settings Check
We validate if a
KeepAliveTime DWORD value exists under
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters and verify that it is set to a recommended value.
KeepAliveTime should be set to 30 minutes or no less than 15 minutes. If there's no entry in the registry for
KeepAliveTime then the value is 2 hours. This value, if not set correctly, can affect both connectivity and performance. You must make sure that the load balancer and any other devices in the path from client to Exchange be set correctly.
The goal is to set Exchange with the lowest value so that client sessions when ended, are ended by the Exchange and not by a device.
Client -> Firewall (1 hour) -> NLB (40 minutes) -> Exchange Servers (20 Minutes)
