How to use psexec to remotely update machines time (from domain)?

In my previous posts you can find info how to install psexec. When you’re already done with this process, you can start updating clock settings on remote machines.

Set time

psexec64 -s /user:domain\user -i \\remote_ip net time \\domain_controller /set /y

Will output:

Bieżąca godzina na \\domain_controller to 2018-08-28 09:55:00.

At least in polish Windows 😀

Check time

psexec64 -s /user:domain\user -i \\remote_ip cmd /c time /t

Will output:

11:18
