查询当前用户是否为域用户

两种方法:

BOOL IsDomainUser()	// 这个方法实际上会查询网络
{
	uint8* Buf = NULL;
	uint8* Buf2 = NULL;

	static BOOL IsDomain = FALSE;
	static BOOL bInit = FALSE;

	if(!bInit)
	{
		DWORD Result = NetGetDCName(NULL, NULL, &Buf);

		if(Result == NERR_Success)
		{
			IsDomain = TRUE;
		}
		bInit = TRUE;

		if(Buf) NetApiBufferFree(Buf);
	}

	return IsDomain;
}

或者读注册表

BOOL IsDomainUser()
{
	DWORD dwType = REG_SZ;
	TCHAR szDomain[MAX_PATH];
	DWORD cbValueSize = sizeof(szDomain);

	if(ERROR_SUCCESS != SHGetValue(HKEY_CURRENT_USER, L"Volatile Environment", L"USERDNSDOMAIN",
		&dwType, szDomain, &cbValueSize ) )
		return FALSE;

	return TRUE;
}
