how to get the user accounts and buit in security principles in windows

Question

i want to retrieve the list of user and local service and network service

Answer 1

You can do this via WSH. Here is an example in JavaScript: http://www.winscripter.com/WSH/ADSI/56.aspx

and a sample in C#: http://www.geekzone.co.nz/chakkaradeep/3938

I found several answers on BING by searching win32 list user accounts

And finally a sample from Microsoft: http://gallery.technet.microsoft.com/ScriptCenter/en-us/827623f5-eb55-4035-8f57-25c4afb444cd

Answer 2

WMI has a Win32_UserAccount class, but enumerating it looks like it produces the same list as NetEnumUsers, which only produces (more or less) "Normal" accounts, not the built in security principals like "Local Service" and "Network Service".

You can retrieve everything with NetLocalGroupEnum and NetLocalGroupGetMembers, but you'd have to do it from something that lets you work with the Win32 API directly, not (at least AFAIK) via WMI. In case that's still useful, here's a bit of sample code that lists groups and members:

#define UNICODE 
#include <windows.h>
#include <lmaccess.h>
#include <lmapibuf.h>

#include <iostream>

int main() {

    LOCALGROUP_INFO_0 *l_info;
    DWORD read;
    DWORD total;

    NetLocalGroupEnum(NULL, 
                    0, 
                    (unsigned char **)&l_info,
                    MAX_PREFERRED_LENGTH,
                    &read,
                    &total,
                    NULL);

    std::wcout << L"Local Groups\n";

    for (int i=0; i<read; i++) {
        std::wcout << l_info[i].lgrpi0_name << std::endl;

        LOCALGROUP_MEMBERS_INFO_1 *members;
        DWORD entries, total_entries;

        NetLocalGroupGetMembers(NULL, 
                                l_info[i].lgrpi0_name, 
                                1,
                                reinterpret_cast<BYTE **>(&members),
                                MAX_PREFERRED_LENGTH,
                                &entries, 
                                &total_entries,
                                NULL);

        for (int mem_num = 0; mem_num<entries; mem_num++)
            std::wcout << L"\t" << members[mem_num].lgrmi1_name << L"\n";
        NetApiBufferFree(members);
    }


    NetApiBufferFree(l_info);

    GROUP_INFO_0 *g_info;

    NetGroupEnum(NULL, 
                0, 
                (unsigned char **)&g_info,
                MAX_PREFERRED_LENGTH,
                &read,
                &total,
                NULL);

    std::wcout << L"\nGlobal Groups\n";

    for (i=0; i<read; i++)
        std::wcout << g_info[i].grpi0_name << std::endl;

    NetApiBufferFree(g_info);
    return 0;
}
