The problem statement is the rate of RST=1 (in TCP packet) error is high (7% of all packets) in our server (Windows Server 2012 R2).
We found that this error was in TCP Handshaking after sending SYN=1 from the client.
To consider more, we use logman with Microsoft-Windows-HttpService provider and after considering logs in detail,
found some errors which their reason is FastSendRespondFailed.
Hence, the question is What is the meaning of FastSendRespondFailed?
P.S. roundabout 100 per/sec requests on IIS and (PerfMon -> TCPV4 -> Connection) Established shows 1500
