Changing Application Pool Identity for IIS 7.5

IIS7.5 includes a new identity type, ApplicationPoolIdentity, and sets it as the default identity for application pools.

On IIS 7.5, PBDotnet4AppPool also uses ApplicationPoolIdentity as its default identity value, but some Web Forms application features—such as creation of permanent user accounts, SSL authentication, and DataWindow Print and SaveAs commands—fail with this identity. You can avoid these issues by changing the PBDotnet4AppPool identity to NetworkService:

  1. In IIS Manager, select Application Pools.
  2. From the list of application pools, right-click PBDotnet4AppPool and select Advanced Settings.
  3. In the Process Model section, change the identity property from ApplicationPoolIdentity to NetworkService, and click OK.
    Changing this setting affects all applications running in the PBDotnet4AppPool application pool.
