Hello

I am running iperf tcp throughput test between multiple windows 2012 servers (in a mesh) connected via a switch and I noticed wreddrops on my switch. I am wondering if you can let me know how to setup the dc-tcp settings on the window server. Currently I have enabled ECN on the windows server as show below. Any help in providing suggestions on how to avoid the drops would be greatly appreciated.

PS C:\Users\Administrator> netsh interface tcp show global
Querying active state...
