The registry key that is mentioned in the “Resolution” section is applicable only to SMB 1.0. To communicate over the SMB2.0 protocol, or CIFS (Common Internet File System), you do not have to set the registry key. SMB 2.0 allows for the functionality described in this article to work by default without additional configuration. Computers that run Windows Server 2008, Windows Server 2008 R2, Windows Vista, and Windows 7 support both SMB 1.0 and SMB 2.0. Windows includes an SMB client component (Client for Microsoft Windows) and an SMB server component (File and Printer Sharing for Microsoft Windows). By default, SMB 2.0 is the file sharing protocol that is used when both client and server support it.

All other music … If you have a Windows server 2008 with hostname (NetBIOS Name) Pluto (pluto.cromb.info as FQDN) and that server have a shared resource called Saturn and instead to use the UNC path \ \Pluto\Saturn you would like to use the UNC path \ \Mars\Saturn, where Mars (mars.cromb.info) is an alias DNS (CNAME) for Pluto, then you need to follow the following recipe:

  • for clients with Windows 2008/Vista/7: creates the DNS alias (CNAME) called Pluto (pluto.cromb.info) associated to the server Mars (mars.cromb.info);
  • for clients with Windows 2000/2003/XP:
    • creates the DNS alias (CNAME) called Pluto (pluto.cromb.info) associated to the server Mars (mars.cromb.info);
    • connected to server Pluto with the credentials of a user with administrative rights on the server;
    • start Registry Editor (Regedt32.exe);
    • locate and click the following key in the registry: HKEY_LOCAL_MACHINE\System
      \CurrentControlSet\Services\LanmanServer\Parameters
    • on the Edit menu, click Add Value, and then add the following registry value:
      Value name: DisableStrictNameChecking
      Data type: REG_DWORD
      Radix: Decimal
      Value: 1
    • quit Registry Editor;
    • restart the server Pluto.

Once you restarted the server Pluto, execute from the Command Prompt of Pluto the following commands: setspn -a host/Mars Pluto and setspn -a host/mars.cromb.info Pluto Or more generally: setspn -a host/<CNAME_Server> <NetBIOS_Name_Server> and setspn -a host/<CNAME_FQDN_Server> <NetBIOS_Name_Server>

Now to access the shared resource (SMB share) Saturn you can use or the UNC path \ \Pluto\Saturn, or the UNC path \ \Mars\Saturn.

This recipe is good for Windows 2000/2003/2003R2 (Windows 2000 should have installed Service Pack 4) and Windows 2008/2008R2. Note that the command setspn.exe is not pre-installed on Windows 2003R2, but  is part of the Windows 2003 Support Tools.
