Question

I’ve been trying Node.js running in Windows Azure Emulator, but unfortunatelly it isn’t working. Of course, I started from beginning, Hello World application, following steps in this tutorial.

I followed the steps below with 4 different computers and in all cases the page didn’t show anything.

• I opened Windows PowerShell environment as Administrator.
• I created node directory
• I entered the command: PS C:\node> New-AzureService tasklist
• I entered the command: PS C:\node\tasklist> Add-AzureNodeWebRole

Here, my application was created with the code above:

var http = require('http');
var port = process.env.port || 1337;
http.createServer(function (req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello World\n');
}).listen(port);

• And finally, I entered the command: PS C:\node\tasklist\WebRole1> Start-AzureEmulator -launch

Now I was supposed to see my hello world page. The question is, if somebody had success with the given tutorial? And what Am I doing wrong?

Answer 1

I had your exact same error and looking for a long time on the Internet I found this post.

Just to summarize, the problem is that there’s a script inside Node package for Azure that’s trying to grant permissions for “Network Service” to the web root directory.
However my system language is it-IT, so I don’t have a user called “Network Service”.

So you need to edit the script. If your application path is C:\node\tasklist then the script is located at

C:\node\tasklist\local_package.csx\roles\WebRole1\approot\bin\setup_web.cmd

Just change this line:

icacls ..\ /grant "Network Service":(OI)(CI)W

with this:

icacls ..\ /grant "NetworkService":(OI)(CI)W

This worked for me!
