ProcessModelIdentityType Enumeration
IIS 7.0
Specifies the process model identity of an application pool.
Assembly: Microsoft.Web.Administration (in Microsoft.Web.Administration.dll)
The values of this enumeration enable you to configure your application pools to run under the security context of an existing security account or a custom account. If you configure the process model to use the SpecificUser value, you must also configure the UserName and Password properties of the ApplicationPoolProcessModel class.
