Ansible | winrm send_input failed on ping test

I´m trying to make a simple win_ping from ansible master to my Windows 2012 R2 server host.

It has a process that uses 100% of my processor and that will not change for now.

When i stop this process, the win_ping pass. But when it´s running i got:

# ansible ocr -m win_ping
 [WARNING]: FATAL ERROR DURING FILE TRANSFER:

BPOCSCOCR02 | FAILED! => {
    "msg": "winrm send_input failed; \nstdout:
    {\"changed\":false,\"ping\":\"pong\"}\r\n\nstderr "

Can anyone think on a workaround for this?

Thanks in advance.
