winrm.exceptions.UnauthorizedError: 401 Unauthorized. basic auth failed

Hello I am a new bee to Python .. Just putting baby steps into Python world.

Here is what I am trying to do ..

1. I have a RHEL 6.5 host on which I have Python 2.6.6 installed.
2. I am using a "winrm" module to connect to a remote windows host to execute a command "ipconfig/all".

Code:-

START

!/usr/bin/python

import getpass
import sys
import winrm

user = "username"
host = "x.x.x.x"
print("Enter password for User [%s]" % user)
pw = getpass.getpass()

from winrm.protocol import Protocol
p = Protocol(
endpoint='http://'+host+':5985/wsman',
transport='plaintext',
username=user,
password=pw)
shell_id = p.open_shell()
command_id = p.run_command(shell_id, 'ipconfig', ['/all'])
std_out, std_err, status_code = p.get_command_output(shell_id, command_id)

print std_out
print std_err
print status_code

p.cleanup_command(shell_id, command_id)
p.close_shell(shell_id)

END

I am getting the following error when executing the above script .. Could anyone please help..

ERROR:-

Traceback (most recent call last):
File "./windows.py", line 18, in
shell_id = p.open_shell()
File "/usr/lib/python2.6/site-packages/winrm/protocol.py", line 118, in open_shell
