Ansible windows async issue.

[Sreenivas Chokkarapu]

Hi guys,

I'm trying to use the ansible's async feature to speed up the deployment process. Basically, this a windows

deployment occurs in 2 stages: 1) analysis deployment (7hrs - 6 vms) 2) head deployment (6hrs - 1 vm). 

I'm trying to run these deployments in parallel. In test env, there are only 2 analysis servers, 1 head server.

The problem is that analysis deployment happens only on one of analysis server, but doesn't seems to deploy on the another analysis server; the head deployment is fine too.In another env, (total 3 vms), it missed out deployment on the head vm. 

Here is the play:

- name: legacy Installation (Analysis server)

  win_shell: >

    {{ script_dir }}\\Installapp.ps1

    '4. Analysis Server'

    {{ headnode }}

    {{ ansible_domain }}\{{ ansible_user }}

    {{ ansible_password }}

  async: 25200

  poll: 0

  register: analysis_deployment

  when: "'risklink17-analysis' in group_names"

- debug: var=analysis_deployment

  when: "'risklink17-analysis' in group_names"

- name: legacy Installation (Head server)

  win_shell: >

    {{ script_dir }}\\Installapp.ps1

    '5. Job Server and Database Server'

    {{ headnode }}

    {{ ansible_domain }}\{{ ansible_user }}

    {{ ansible_password }}

    -skip_mail

  async: 21600

  poll: 0

  register: head_deployment

  when: "'risklink17-head' in group_names"

- debug: var=head_deployment

  when: "'risklink17-head' in group_names"

- name: Waiting for analysis deployment to complete...

  async_status: jid={{ analysis_deployment.ansible_job_id }}

  register: analysis_result

  until: analysis_result.finished

  retries: 420

  delay: 60

  when: "'risklink17-analysis' in group_names"

- name: Analysis deployment completed, waiting for Head deployment.

  async_status: jid={{ head_deployment.ansible_job_id }}

  register: head_result

  until: head_result.finished

  retries: 360

  delay: 60

  when: "'risklink17-head' in group_names"

  

On the vm, where the deployment missed, i see this error from the eventviewer app:

```

Settings: Could not read key from registry (Exception from HRESULT: 0x80040150 (REGDB_E_READREGDB)) 

Details: 

    ExceptionClass=COMException

    ErrorCategory=

    ErrorId=

    ErrorMessage=Could not read key from registry (Exception from HRESULT: 0x80040150 (REGDB_E_READREGDB))

```

I'm using ansible version: 2.2.1.0; any help on this would be much appreciated.
