Here's the setup, I have a small lab that connects to the server on the other side of the building, yesterday out of the blue 2 of the machines cannot login to the server using the default login of "Student."

When prompted for credentials and they are entered I receive the following message "the trust relationship between this workstation and the primary domain failed" Now, with my limited knowledge I figured that if i login to the machine locally and unjoin and rejoin it to the domain this might solve the issue. Except one problem, in windows 7 you can't get to that screen without entering the Admin credentials. (which i have) After entering the credentials I still receive the same message and am prompted for the credentials again. I'm stuped, any help would be greatly appreciated, again thanks and sorry for being so unbelievably green in the server world, I'm trying to learn as much as I can right now as I go.

To unjoin a WS on Win7 you just need a LOCAL ADMIN account, not the admin domain :)

Why is it prompting me for the Domain admin credentials then ? I am already logged in as the local admin, but when i click change setting button under the "Computer name, Workstation and domain setting it prompts me for the domain credentials. I'll try and manually enter the local admin credentials but i'm pretty sure I tried that yesterday and i didn't work. thanks again. I'm sure I'll have many many questions in the future.
 
Mhhh probably because the object "computer" must be deleted on AD... but anyway... I'm pretty sure you can do it without using domain users.

ok, so i tried to use the local credentials but when i did i get a error message saying this process requires elevation. But i am on the highest access i can have being the Local Admin, (thats what i'm logged in as) I'm at a loss.
 
mhhhh sorry but if I'm on a domain, and I want to switch on WORKGROUP, I don't see WHY should I provide domain credentials...

Try in safe mode... :blink:
 
I'm just gave up and took the simi-easy way out and am trying to just re-image the unit, i'll report back and let you know if im still having problems, thanks again for all your help.
 
So long story short, somehow i fixed the original issue but made it transfer to the computer that i grabbed the image from, don't ask how, but it happened. I spent hours trying to fix the issue, eventually i just tried imaging that unit again from a different image that I mad from a computer that I un-joined from the domain before I took the image. It worked for now, we'll see if it holds up. Thanks again for your help.
