Allowing server machine to use filesharing with itself via the DNS Alias (BackConnectionHostNames) (Windows Server 2008 & 2012)

This change is necessary for a DNS alias to work with filesharing from a machine to find itself. This creates the Local Security Authority host names that can be referenced in an NTLM authentication request.
To do this, follow these steps for all the nodes on the client computer:
  1. To the registry subkey HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0, add new Multi-String Value BackConnectionHostNames
  2. In the Value data box, type the CNAME or the DNS alias, that is used for the local shares on the computer, and then click OK.
    • Note: Type each host name on a separate line.
