問題描述︰ DC authentication issue -DC generate Event id 675 (0x19) from Win2k8 machine
解決方式︰ 這是Windows 2003 和Windows 2008 在驗証協定上設計的不同點，有兩種方式可以避免: 1. We can check "Do not require Kerberos pre-authentication" of User account in AD user & computer console, we will not longer get the same event for users. We can reference to KB: http://support.microsoft.com/kb/954415/en-us
2. Due to this shows that issue is with pre-authentication from machines. And we identified that issue was only with Vista and Windows 2008 machines and not with Windows XP and Windows 2003 machines. Because of design change pre-authentication is not forced on Vista and Windows 2008 machines. We forced pre-authentication on Windows Vista machines using following registry value: HKLM\System\CurrentControlSet\Control\LSA\Kerberos\Parameters Value Name = DefaultEncryptionType Type = Reg_DWORD Value Data = 0x17(23)
The following list provides information about which operating systems support the Terminal Services Easy Print driver, and whether additional configuration is required.
