C:\Users\SJ046\Desktop\Sim\Test>mpiexec -machine hosts.txt test_mpi
[mpiexec@SJ046] HYDI_bstrap_service_launch (bstrap\service\service_launch.c:432): server rejected credentials
[mpiexec@SJ046] remote_launch (bstrap\src\intel\i_hydra_bstrap.c:607): error launching bstrap proxy
[mpiexec@SJ046] single_launch (bstrap\src\intel\i_hydra_bstrap.c:665): remote launch error

[mpiexec@SJ046] HYD_print_bstrap_setup_error_message (intel\i_mpiexec.c:1027): error setting up the bootstrap proxies
[mpiexec@SJ046] Possible reasons:
[mpiexec@SJ046] 1. Host is unavailable. Please check that all hosts are available.

My Intel MPI version is
Intel(R) MPI Library for Windows* OS, Version 2021.6 Build 20220227
Copyright 2003-2022, Intel Corporation.

I tried that link

stuck at Active Directory* Setup

I can't find Active Directory Users and Computers

so I tried setup that Fig1

I can't setup that....

Would using Windows 10 Home edition be a reason?

@BackSunho regarding active directory setup I have to redirect you to MS support.
