Ansible WinRM: Configure Windows Remote Management Connection (Complete Guide)

Ansible + Windows: How It Works

Ansible manages Windows machines over WinRM (Windows Remote Management) instead of SSH. No agent is installed on Windows — Ansible sends PowerShell commands over WinRM and collects results.

┌──────────────┐    WinRM/HTTPS     ┌──────────────┐
│   Control     │ ──────────────────▶│   Windows     │
│   Node        │   (port 5986)      │   Server      │
│   (Linux)     │                    │               │
└──────────────┘                    └──────────────┘
   Ansible + pywinrm                  WinRM enabled

Requirements: • Control node: Linux or macOS (Ansible doesn't run on Windows as control node) • Managed nodes: Windows Server 2016+ or Windows 10+ • Python package: pywinrm • WinRM enabled on Windows hosts

Enable WinRM on Windows

PowerShell Script (Recommended)

# Run as Administrator on each Windows host
# Download and run the Ansible WinRM setup script
$url = "https://raw.githubusercontent.com/ansible/ansible-documentation/devel/examples/scripts/ConfigureRemotingForAnsible.ps1"
$file = "$env:temp\ConfigureRemotingForAnsible.ps1"
(New-Object -TypeName System.Net.WebClient).DownloadFile($url, $file)
powershell.exe -ExecutionPolicy ByPass -File $file

Manual Setup

# Enable WinRM
Enable-PSRemoting -Force
# Set up HTTPS listener (recommended for production)
$cert = New-SelfSignedCertificate -DnsName $env:COMPUTERNAME -CertStoreLocation Cert:\LocalMachine\My
winrm create winrm/config/Listener?Address=*+Transport=HTTPS "@{Hostname=`"$env:COMPUTERNAME`";CertificateThumbprint=`"$($cert.Thumbprint)`"}"
# Allow basic auth (for testing only)
winrm set winrm/config/service/auth '@{Basic="true"}'
# Allow unencrypted (NEVER in production)
# winrm set winrm/config/service '@{AllowUnencrypted="true"}'
# Set execution policy
Set-ExecutionPolicy RemoteSigned -Force
# Configure firewall
New-NetFirewallRule -Name "WinRM-HTTPS" -DisplayName "WinRM over HTTPS" -Enabled True -Direction Inbound -Protocol TCP -LocalPort 5986 -Action Allow

Enable WinRM via Group Policy (Domain)

Computer Configuration → Administrative Templates → Windows Components → Windows Remote Management → WinRM Service
  → Allow remote server management through WinRM → Enabled
  → IPv4 filter: * (or specific subnets)

FAQ

Can Ansible run on Windows as a control node?

No. The Ansible control node must be Linux or macOS. You can manage Windows from Linux using WinRM. If you only have Windows, use WSL2 (Windows Subsystem for Linux) to run Ansible.

WinRM or SSH for Windows?

WinRM is the standard and best-supported connection method. Windows 10+ includes OpenSSH Server, and Ansible can use ansible_connection: ssh with it. However, WinRM provides better integration with Windows authentication (NTLM, Kerberos, CredSSP). Use WinRM unless you have specific SSH requirements.

How do I handle reboots?

Use ansible.windows.win_reboot after tasks that require reboot (Windows Updates, feature installation). Set appropriate reboot_timeout for long updates. Check reboot_required in task results to conditionally reboot.

What about Windows containers?

Ansible manages Windows containers with community.docker collection over WinRM. Docker Desktop or Docker EE on Windows Server works with the same docker_container module.

Conclusion

Ansible automates Windows at scale — IIS, Active Directory, Windows features, software deployment, security hardening, and patch management. Configure WinRM once, and you manage Windows the same way you manage Linux: declarative YAML playbooks, idempotent operations, version-controlled infrastructure. Use Kerberos for domain environments, Chocolatey for package management, and serial for safe rolling updates.
