Web development using ASP.NET 2.0 is more easy, fun and less of coding, many ready made control to use it such as login, gridview, etc.

When i want to create a virtual directory for my web applications using IIS 5.1, i always got messages “Server Application Unavailable”, I’m wondering why this happen, so i look at the event viewer in administrative tool.

The message is “aspnet_wp.exe stop unexpectedly”. I am searching answer for this problem. And finally I’ve got answer.

This problem because i haven’t give permission for my application folder, to do that right click web folder and choose sharing and security, choose security tab and click add button and search for user ASPNET for your local computer.
