The AD server name and AD domain name can be checked in "System Properties" in
Windows. As an example, for Windows 2003 servers, if you see "node1.qnap-test.com" as
the "Full computer name" on the system properties dialog window, the AD server name is
"node1" and NOT "node1.qnap-test.com" and the domain name remains the same as
qnap-test.com.
Windows Server 2008
Check the AD server name and domain name in "Control Panel" > "System" in Windows. In
the system dialog window, the AD server name will appear as the computer name and the
domain name can be found in the domain field.
Note:
 After joining the NAS to the Active Directory, the local NAS users who have access
rights to the AD server should use "NASname\username" to login. AD users should use
their own usernames to login to the AD server.
 For TS-x09 series NAS, if the AD domain is based on Windows 2008 Server, the NAS
firmware must be at least version 2.1.2.
