Access denied
This issue might occur if the authentication configuration in IIS is configured incorrectly for the EnterpriseVault virtual directory, listvaults.asp and usage.asp pages .
The technology provided by the Windows operating system and the applications involved determine the way queries are passed across IIS servers. Since it is not possible to forward the login credentials using Integrated Windows authentication (IWA), Integrated Windows Authentication has to be unchecked and Basic Authentication enabled for the listvaults.asp and usage.asp pages.
By default, only the Vault Service Account (VSA) has access to the Vault Usage Report because of permission issues between Enterprise Vault (EV) and the Vault Database. Follow these steps to resolve this issue:
On the EV server , open the Internet Information Services (IIS) Manager.
