I was greeted this morning by a couple of computers in our network having upgraded to a new version of Windows 10 and of course failing almost immediately afterward as seems to be the norm these days. The error was “the trust relationship between this workstation and domain failed” and of course school was out and it was my day.
Today’s misery seemed to be centered around a couple of machines that suddenly lost trust credentials with my network, which in the past had required me to remove the computer from the domain and rejoin it. However I had a five year old in tow today an managed to piece this together from a technet article, a comment section, and a slightly incorrect but mostly great article here.
First – get in with a local admin account. You set it up with one when you set it up didn’t you? No? Unplug the network and try logging in as that user then and see what you can do.
Next, open powershell as an admin, execute the following two lines
- $credential = Get-Credential
- Reset-ComputerMachinePassword -Server putyourservernamehere -Credential $credential
After entering that first line you’ll get a popup to enter some domain admin credentials, enter them, second line should reestablish trust and you should once again be able to log in.
Hope your Windows 10 May/June update goes smoother than mine, but if you’re greeted with “The trust relationship between this workstation and domain failed” you’ve got a pretty easy fix.
Make sure to have a local admin password handy however as if you don’t have one I’m not entirely sure what your next step is (perhaps unplug network, log in, plug back in, run the above code, enter domain admin info, perhaps that would work).
Hope this helps, most of the info came from the above linked slightly incorrect article.
