How to fix the lost of trust between a workstation and the domain, even when you don't have a locale administrator account on the workstation.
@Linux Guys: i know you know what to do if you see what Windows admins had to do.
@Windows Admins: Boot from your Install CD and go the Command line.
Someone told me that Shift+F10 do the job on Windows 10 Install DVD.
Now you had to copy Files in your System32 Directory
move c:\windows\system32\utilman.exe c:\windows\system32\utilman.exe.bak copy c:\windows\system32\cmd.exe c:\windows\system32\utilman.exe
You replace your original utilman.exe with a renamed copy of cmd.exe.
Reboot your System now.
There are a lot of articles with similar doing through this part, but the problem with lost of domain trust, you can add new users, but you can not gain admin rule to the new user.
So first you had to leave the domain, I found a nice working foo for this on the internet, and want to share it with you.
@echo off start /B /W wmic.exe /interactive:off ComputerSystem Where "Name='%computername%'" Call UnJoinDomainOrWorkgroup FUnjoinOptions=0 start /B /W wmic.exe /interactive:off ComputerSystem Where "Name='%computername%'" Call JoinDomainOrWorkgroup name="WORKGROUP" start /B /W wmic.exe /interactive:off ComputerSystem Where "Name='%computername%'" Call Rename name="standaloneComputer" shutdown.exe /r /t 0 /f
(Tested on Windows10 System)
After your System is rebooted you can add a new user and give him admin rights.
net user temp_admin Pa$$word /add net localgroup administrators temp_admin /add
If you don't use a english windows your administrators group maybe had another name, as example: Administratoren if you using a german windows
Now you can reboot your System and login with .\temp_admin as user and Pa$$word as password after login you can rejoin your Domain.
