Solution

Add DisableLoopBackCheck and DisableStrictNameChecking on SharePoint Server.

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

1. Open Registry editor:  Start | Run | Regedit
2. Add  DisableLoopBackCheck and DisableStrictNameChecking to the registry
    
3. Restart the SharePoint Server
    

Disable Loopback Check

      HKLM\SYSTEM\CurrentControlSet\Control\Lsa
      Dword value: DisableLoopbackCheck
      Value data (Decimal): 00000001

Note: An issue has been found on Enterprise Vault servers that have been configured with Aliases. The use of the fully qualified domain name (FQDN) or a custom host header to browse a local Web site that is hosted on a computer that is running Microsoft Internet Information Services (IIS) 5.1 or IIS 6, generates the error message. HTTP 401.1 - Unauthorized: Logon Failed.

Note: This issue occurs when the Web site uses Integrated Authentication and has a name that is mapped to the local loopback address. Windows Servers include a loopback check security feature that is designed to help prevent reflection attacks on your computer. Therefore, authentication fails if the FQDN or the custom host header that is used does not match the local computer name. Disabling the loopback check, clears the "Access Denied" errors in the VAC and Event ID 40974 in the Event Logs.


Disable Strict Name Checking

      HKLM\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters
      Dword value: DisableStrictNameChecking
      Value data (Decimal): 00000001

Note:  Enterprise Vault utilizes DNS Aliases for optimized design and scalability. When a client computer connects to a Windows server by using an alias name, the client may receive an error message. This problem tends to occur when trying to connect to the server by using a CNAME alias that is created in the DNS zone. The server is not "listening" on the alias, and therefore is not accepting connections to that name. By requesting to disable strict name checking, this issue is resolved.
