+# ⚠️ URGENT: Docker Desktop DNS Configuration Required
+
+## Problem
+Docker Desktop is still using the old DNS server (10.0.2.3) which is timing out. The WSL2 DNS fix we applied helps the host, but **Docker Desktop runs in its own VM and needs separate DNS configuration**.
+
+## Solution: Configure Docker Desktop DNS
+
+### Step 1: Open Docker Desktop
+1. Look for the Docker Desktop icon in your Windows system tray (bottom right)
+2. Right-click and select "Settings" or open Docker Desktop
+
+### Step 2: Navigate to Docker Engine Settings
+1. In Docker Desktop, click the **Settings** (⚙️) icon in the top right
+2. In the left sidebar, click **"Docker Engine"**
+
+### Step 3: Add DNS Configuration
+1. You'll see a JSON configuration editor
+2. **Add or update** the `dns` field in the JSON:
+
+**If the JSON is empty or minimal:**
+```json
+{
+  "dns": ["8.8.8.8", "8.8.4.4", "1.1.1.1"]
+}
+```
+
+**If there's already content, add the dns line:**
+```json
+{
+  "builder": {
+    "gc": {
+      "enabled": true
+    }
+  },
+  "dns": ["8.8.8.8", "8.8.4.4", "1.1.1.1"],
+  "experimental": false
+}
+```
+
+### Step 4: Apply and Restart
+1. Click **"Apply & Restart"** button
+2. Wait for Docker Desktop to restart (this takes 30-60 seconds)
+
+### Step 5: Verify
+After Docker Desktop restarts, test in WSL2:
+```bash
+cd /home/intlc/projects/quorum-test-network
+docker pull alpine:latest
+```
+
+If this works, the DNS is fixed!
+
+## Alternative: Restart WSL
+If you can't access Docker Desktop settings right now:
+1. From Windows PowerShell (as Administrator):
+   ```powershell
+   wsl --shutdown
+   ```
+2. Restart your WSL terminal
+3. Try the network again
+
+## Quick Reference
+- **Docker Desktop Settings Location**: Settings → Docker Engine
+- **DNS Servers to Add**: `["8.8.8.8", "8.8.4.4", "1.1.1.1"]`
+- **After Configuration**: Click "Apply & Restart"
+
+## Why This is Needed
+Docker Desktop runs in a separate VM from WSL2. The DNS configuration we applied to WSL2 doesn't automatically apply to Docker Desktop's VM. Docker Desktop needs its own DNS configuration.
