# IIS Handlers Section Unlock - Manual Guide

## Problem
Error: "This configuration section cannot be used at this path. This happens when the section is locked at a parent level."

## Solution 1: Using Script (Easiest)
Run `UNLOCK-IIS-HANDLERS.bat` as Administrator

## Solution 2: Manual Unlock via IIS Manager

### Step 1: Open IIS Manager
- Windows + R → `inetmgr` → Enter

### Step 2: Unlock Handlers Section
1. **Select Server** (root level - your computer name at top)
2. **Double-click "Feature Delegation"** (in Management section)
3. Find **"Handler Mappings"** in the list
4. **Right-click** → **"Read/Write"** (or click "Read/Write" in Actions pane)
5. **Confirm** if prompted

### Step 3: Restart IIS
- Command Prompt (Admin): `iisreset`
- Or restart Application Pool in IIS Manager

### Step 4: Test
- Browser: `http://localhost`

## Solution 3: Using PowerShell (Advanced)

```powershell
# Run as Administrator
Import-Module WebAdministration
Set-WebConfigurationProperty -PSPath "MACHINE/WEBROOT/APPHOST" -Filter "system.webServer/handlers" -Name "overrideMode" -Value "Allow"
iisreset
```

## Solution 4: Edit applicationHost.config (Advanced)

1. Open: `C:\Windows\System32\inetsrv\config\applicationHost.config`
2. Find: `<section name="handlers" overrideModeDefault="Deny" />`
3. Change to: `<section name="handlers" overrideModeDefault="Allow" />`
4. Save and restart IIS

## Verify iisnode Installation

Check if iisnode is installed:
- Look for: `C:\Program Files\iisnode\`
- Or check IIS Modules: IIS Manager → Server → Modules → Look for "iisnode"

If not installed:
- Download: https://github.com/Azure/iisnode/releases
- Install and restart IIS

## After Unlocking

1. Restart IIS: `iisreset`
2. Test website: `http://localhost`
3. Check logs if errors: `dist\iisnode\` folder
