I'm attempting to mass disable Explicit Network Congestion Notification on a group of Windows Server 2012r2 servers hosted in AWS EC2. I'm using the Salt Stack configuration management tool. When I execute the command to disable ECN locally, on a server from an elevated command prompt:
netsh int tcp set global ecncapability=disabled
it works correctly -- ok
When I execute it from the salt master:
salt -G "os:windows" cmd.run 'netsh int tcp set global ecncapability=disabled'
It returns
Set global command failed on IPv4 The parameter is incorrect.
Other netsh commands work correctly. I've attempted several other fixes, including executing with the netsh in C:\windows\system32\netsh.exe, as well as the C:\windows\sysWOW64\netsh.exe. Neither work, both produce the same errors.I'm running Salt Master version 2016.11.4 Carbon.
