Introduction
In our final guide for the series we'll walk through the process of configuring Azure Arc-enabled Windows servers using an Azure VM extension. We'll cover essential steps like installing IIS and blocking the legacy Azure Log Analytics agent. Whether you're a system administrator new to Azure Arc or looking to refine your configuration, this post will provide valuable insights.
Step-by-Step Guide
Installing IIS
- Log into your Windows VM: Establish a Remote Desktop connection to your Windows VM.
-
Open PowerShell ISE: Launch Windows PowerShell Integrated Scripting Environment (ISE) with administrative privileges.
-
Create the installation script:
- Paste the following script into PowerShell ISE: ```powershell
Install-WindowsFeature -name Web-Server -IncludeManagementTools
Remove-Item -Path 'C:\inetpub\wwwroot\iisstart.htm'
Add-Content -Path 'C:\inetpub\wwwroot\iisstart.htm' -Value "$env:computername"
* Save the script as `Install_IIS.ps1` in your Documents folder.
4. **Create an Azure storage account:**
* Navigate to the Azure portal and create a new storage account.
* Configure the storage account with your Subscription, Resource Group, and create a globally unique name.
* Select Locally Redundant Storage (LRS) for redundancy and click "Review + Create".
5. **Create a storage container:**
* Within the storage account, click on "Container" to create a folder for the script.
* Click on "+ Container"
* Create a name for the storage container then click on "Create"
6. **Upload the script:**
* Upload the `Install_IIS.ps1` script to the created storage container.
7. **Configure the Azure VM extension:**
* In the Azure portal, navigate to your Azure Arc-enabled machine.
* Underneath "Settings" click on "Extensions"
* In the Extensions page, search for and add "Custom Script Extension for Windows - Azure Arc."
* Configure the extension to use the storage account and container containing the script.
8. **Verify IIS installation:**
* Wait for the deployment to complete.
* Open a web browser and navigate to `https://localhost`. You should see the server's name. Alternatively, check the contents of `C:\inetpub\wwwroot\iisstart.htm`.
#### Blocking the Legacy Azure Log Analytics Agent
1. **Open Command Prompt:** Launch Command Prompt on the Windows VM.
2. **Check current configuration:**
* Run `azcmagent config list` to view the current configuration.
3. **Block the agent:**
* Execute `azcmagent config set extensions.blocklist "Microsoft.EnterpriseCloud.Monitoring/MicrosoftMonitoringAgent"` to block the agent.
4. **Verify the change:**
* Run `azcmagent config list` again to confirm the blocklist entry.
**Conclusion:**
Congratulations on completing this guide! You've successfully transformed your Windows Server into a managed Azure Arc-enabled machine. By integrating Azure Policy, Microsoft Defender for Cloud, Azure Monitor, and Azure Update Manager, you've established a strong foundation for security, compliance, and management.
