The Site Name machine setting should be configured correctly. Specifies the Active Directory site to which computers belong. An Active Directory site is one or more well-connected TCP/IP subnets that allow administrators to configure Active Directory access and replication. To specify the site name for this setting, click Enabled, and then enter the site name. When the site to which a computer belongs is not specified, the computer automatically discovers its site from Active Directory. If this setting is not configured, it is not applied to any computers, and computers use their local configuration. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Net Logon\Site Name (2) KEY: HKLM\Software\Policies\Microsoft\Netlogon\Parameters\SiteName
