Might need to reinstall then.

@Lakshmana Need to reinstall. Should have awhile ago if this was known. Better to do it in a controlled environment than have something like this happen

How can their be a trust relationship error if you haven't joined the domain yet?

You need to unjoin the domain
You need to fix the time
You need to rename your computer
You need to rejoin the domain

@scottalanmiller The user who already worked in that machine can login with the old password.What can be the troubleshooting done here ??

Cached credentials.
The PC can't authenticate anyone against AD, so it's relying on itself.
Domain admins as far as I know have to be authenticated against the domain. So, unless you know the local admin password, you are going to have a difficult time.

Also, check AD for the old name and delete it if you find it. No sense keeping an old broken record.

There are other ways, apparently to fix without the unjoin/rejoin but I've never had them work on the multiple attempts that I've made to use them.

There is some good information here: https://community.spiceworks.com/topic/594585-the-trust-relationship-between-this-workstation-and-the-primary-domain-failed

You can simply unplug the Ethernet cable, reboot and login with the domain admin login. It then cant check the domain on reboot and should let you in. You can then fix the time, remove it, make a local admin user, reboot, rejoin to domain. done this many times in the past, if I am understanding you.

I got the impression that he doesn't have any admin passwords.

Ah, if that is the case then there is an option to use the NT Offline PW reset bootable iso and change the local administrator pw or blank it. You can then login as the local administrator, and remove the pc from the domain using that account.
That would then require the object to be deleted from AD manually some time in the future. the pc would then also need to be renamed as well I think if you wanted to rejoin it.

If he has no admin password access at all then there is no point in doing anything because even a clean install will require a domain admin password to join the system to the domain.

This only works if a domain admin has logged into the PC in the past - i.e. uses Cached Credentials.

The impression I got was that he doesn't have either a local admin password or a cached domain admin (of course, he might have a cached domain admin, but if he didn't unplug the ethernet, then it would deny him because of the lack of account trust).
