Platform SDK: Get domain name

[Stefan Spenz]

I need to get the domain name for the currently logged on user. ::GetUserName gets me the user name, but how do I get the domain name for that user? Thanks!

With, Win32_LogonSession you will get 'LogonId' use this logonId to query the Win32_LoggedOnUser. After querying 'Win32_LoggedOnUser' you will get all the fields, like - Domain, Name etc Supriya

Use NetWkstaUserGetInfo[^] and retrieve level 1 information, as below. Requires Windows NT 3.1, 2000, XP, Vista.

#include <Windows.h>
#include <lm.h>

std::wstring GetDomainName()
{
WKSTA_USER_INFO_1* workstationInfo;
const NET_API_STATUS status = NetWkstaUserGetInfo(NULL, 1, (LPBYTE*)&workstationInfo);
if (status == NERR_Success)
{
return workstationInfo->wkui1_logon_domain;
NetApiBufferFree((LPBYTE*)&workstationInfo);
}
return std::wstring();
}

Another option is the environment variables USERDNSDOMAIN and USERDOMAIN. Hope that helps.
