Suppose I have many different website created on IIS 7 on Windows 2008 R2. Each of them may have different application pool:
.NET 1.1 .NET 2.0 .NET 3.5 .NET 4.0
What the system account to run all those web app? If the app need to read/write file, need to set up right permission for specific folder, then how can I identify the right account to assign right permission?
