Granting access to IIS 7.5 ApplicationPoolIdentity [duplicate]
Ok I have the solution: When using “ApplicationPoolIdentity” with IIS 7.5 the corresponding user is (a virtual system user): “IIS AppPool\<AppPoolName>” You can grant this user permissions and check security setting by searching for this user. See the full explanation here: http://www.iis.net/learn/manage/configuring-security/application-pool-identities
