win_user is not repeatable

A minimal playbook

---
# vim: set filetype=ansible ff=unix ts=2 sw=2 ai expandtab :
#
# Playbook to configure the environment

- hosts: createuser

  tasks:
    - name: create user
      run_once: true
      win_user:
        name: gary
        password: 'B0bP4ssw0rd123!^'
        password_never_expires: true
        account_disabled: no
        account_locked: no
        password_expired: no
        state: present
        groups:
          - Administrators
          - Users

When I run first time I get:

PLAY [createuser] ************************

TASK [Gathering Facts] *******************
ok: [dsy-demo-mssql02]

TASK [create user] ***********************
changed: [dsy-demo-mssql02]

PLAY RECAP *******************************
dsy-demo-mssql02 : ok=2 changed=1 unreachable=0 failed=0

When I re-run, I get:

PLAY [createuser] ************************

TASK [Gathering Facts] *******************
ok: [dsy-demo-mssql02]

TASK [create user] ***********************
fatal: [dsy-demo-mssql02]: FAILED! => {“changed”: false, “failed”: true, “msg”: “Exception calling "ValidateCredentials" with "2" argument(s): "The network path was not found.\r\n"”}

NO MORE HOSTS LEFT ***********************
to retry, use: --limit @/root/ansible_windows/createuser-playbook.retry

PLAY RECAP *******************************
dsy-demo-mssql02 : ok=1 changed=0 unreachable=0 failed=1

Just trying to work out if there is anything obvious I could be doing wrong.

I have verified that I can login to the created account.

verbose output is not much different:

TASK [create user] *********************************
task path: /root/ansible_windows/createuser-playbook.yml:9
Using module file /usr/lib/python2.6/site-packages/ansible/modules/windows/win_user.ps1
ESTABLISH WINRM CONNECTION FOR USER: local\Administrator on PORT 5986 TO dsy-demo-mssql02
EXEC (via pipeline wrapper)
fatal: [dsy-demo-mssql02]: FAILED! => {
“changed”: false,
“failed”: true,
“msg”: “Exception calling "ValidateCredentials" with "2" argument(s): "The network path was not found.\r\n"”
}

Sorry, meant this for the ansible-project group
