I recently resinstalled Windows 7 on my machine and went back to downloading and installing the tools to help me continue developing node.js windows azure web applications. I followed the instructions given on the node.js azure site:

http://www.windowsazure.com/en-us/develop/nodejs/

and using web installer 4.0 it says I have successfully installed these tools:

• Windows Azure Powershell
• Windows Azure SDK for Node.js - June 2012
• Windows Azure SDK for .Net (VS 2012 RC) - June 2012
• IIS Recommend Configuration

The problem I am experiencing is that when I run the site using powershell e.g:

start-azureemulator -launch

it goes ahead and runs IIS Express, and after several minutes IIS Express crashes with the following information:

I am running 2 instances each time, and both of them crash one after the other. Is anyone experiencing something similar and fix this issue ? Is their an upgrade I need to do ? I've run windows update but it says I've got all the latest updates etc.

Can I tell the powershell cmdlet to use IIS 7 instead of IIS Express? I'm guessing its something to do with IIS Express on my machine.

I did some hunting around and found this person here who experienced a similar problem:

https://github.com/tjanczuk/iisnode/issues/149

I've got a cron job running every 1 second, to check if any website totals need to be updated. Could this be causing IIS Express to crash?

Cheers
