| Platform SDK: Active Directory, ADSI, and Directory Services |
The IADsWinNTSystemInfo interface lets you retrieve the Windows NT® 4.0 system information on a computer running Windows® 2000. Such system information includes user account name, user domain, host name and the primary domain controller of the host machine.
The IADsWinNTSystemInfo interface is implemented on the WinNTSystemInfo object residing in activeds.dll, which comes with the standard installation of ADSI on Windows 2000. You must explicitly create an instance of the WinNTSystemInfo object in order to call the methods on the IADsWinNTSystemInfo interface. This requirement means creating an WinNTSystemInfo instance with the CoCreateInstance function in C/C++:
IADsWinNTSystemInfo *pNTsys;
HRESULT hr = CoCreateInstance(CLSID_WinNTSystemInfo,
NULL,
CLSCTX_INPROC_SERVER,
IID_IADsWinNTSystemInfo,
(void**)&pNTsys);
You can also use the New operator in Visual Basic®:
Dim ntSys as New WinNTSystemInfo
Or you can call the CreateObject function in a scripting environment, supplying "WinNTSystemInfo" as the ProgID:
Dim ntSys
Set ntSys = CreateObject("WinNTSystemInfo")
