ASP.NET How to configure Network Tracing with TextWriterTraceListener

Setting up network tracing in ASP.NET is really simple, and takes less than 30 seconds to set up. Here is the article on MSDN:http://msdn.microsoft.com/en-us/library/ty48b824.aspx

Unfortunately for me, after completing the steps, I was not able to locate the log file (for me network.log) anywhere on the web server. I searched the directories where a log file might appear: Windows, System32, LogFiles and the root directory of the site with no luck.

After reading around the Internet, I found the solution: Grant the NETWORK user Write access to your site.

Here is a simple set of steps to set up network tracking, and have it work properly:
1. Follow the steps listed in this article on MSDN: http://msdn.microsoft.com/en-us/library/ty48b824.aspx
2. Grant the NETWORK user Write access to your site.

After completing these steps, the trace log appeared in the root directory of the site.

Here is a sample of the output from the trace log:
