Turns out that there are some clever and powerful tools in Visual Studio 2005 and 2008 for working with the Management Classes (although couldn’t find it in the “Standard Edition” installed on this machine, definitely exists in my laptop’s Visual Studio). You can use Server Explorer to navigate a treeview to your management class (in this example, the Printers node), right-click on it and select “Generate Managed Class”. This will automagically create a strongly-typed C#.Net class representing the object model of the WMI Printers Class, with all its properties and methods.

Pointer to a PDOMAIN_CONTROLLER_INFO value that receives a pointer to a DOMAIN_CONTROLLER_INFO structure that contains data about the domain controller selected. This structure is allocated by DsGetDcName. The caller must free the structure using the NetApiBufferFree function when it is no longer required.

If you want to find the user logged in to the workstation, consider instead a WMI query ("select UserName from Win32_ComputerSystem"), which has certain advantages (runs faster, less ambigious results, doesn't require Interop if using .Net 2.0 System.Management namespace, etc.)
