Web Service Identity (Reporting Services Configuration)
Use this page to view the service account information used by the Report Server Web service. The Report Server Web service account is configured when you create the Report Server virtual directory.
This page appears when you use Internet Information Services (IIS) 5.0 or 5.01, or if you are running IIS 6.0 in isolation mode. If you are using these versions of IIS, you cannot configure the Report Server Web service identity. It always runs under the ASP.NET process identity.
