IT:AD:Infrastructure:IIS:Concepts:ApplicationPoolIdentity

Beginning in IIS 7.5, the default identity for an application pool is ApplicationPoolIdentity.
* It is a Managed Service Account (ie a pseudo identity) that you won't find in the local usrs of the computer.

When a web application is created using Visual Studio, the App_Data folder is not automatically configured to allow write access for ApplicationPoolIdentity. Therefore the attempt to write to the App_Data folder will fail. </panel> ## Process ## Either create a unique AppPool identity and grant it rights, or stick with the ApplicationPoolIdentity and grant it rights to the App_Data folder: ApplicationPoolIdentity ## Resources ## http://support.microsoft.com/kb/2005172
