Getting to know ApplicationPoolIdentity

If you have not used Windows Server 2008 R2 much, you may not have noticed that there is a new account available for IIS called ApplicationPoolIdentity

If you have been working with IIS for any length of time, you are probably most familiar with the Network Service account.  Well, there were some limitations and issues that were encountered when multiple applications were utilizing the Network Service account, particularly 3rd party applications running in IIS such as Perl, PHP etc.  Therefore, the Microsoft team introduced the ApplicationPoolIdentity account to address these needs.

You can read more about the ApplicationPoolIdentity account here:
