IADsADSystemInfo interface

The IADsADSystemInfo interface retrieves data about the local computer if it is running a Windows operating system in a Windows domain. For example, you can get the domain, site, and distinguished name of the local computer.

The IADsADSystemInfo interface is implemented on the ADSystemInfo object residing in adsldp.dll, which is included with the standard installation of ADSI on Windows 2000. You must explicitly create an instance of the ADSystemInfo object in order to call the methods on the IADsADSystemInfo interface. This requirement amounts to creating an ADSystemInfo instance with the CoCreateInstance function in C/C++.

IADsADSystemInfo *pADsys;
HRESULT hr = CoCreateInstance(CLSID_ADSystemInfo,

You can also use the New operator in Visual Basic.

Dim adSys as New ADSystemInfo

Or you can call the CreateObject function in a scripting environment, supplying "ADSystemInfo" as the ProgID.

Dim adSys
Set adSys = CreateObject("ADSystemInfo")


The IADsADSystemInfo interface has these methods.
