So I have this school computer. And I got help from a friend who managed to make the program sethc.exe to become an command promt that you could make pop-up by using sticky keys and from there I created a local admin account off the school domain network. My school computer is hooked up to a domain network and when I would login to my school account(non-admin) I would write ad.stockholm.se\ab63124 Im from Sweden. Hence the "stockholm" and ".se". ab63124 is my user name. After that I type in my password which I know is correct. But the problem is that It doesn't work. For example. Before the summer when I was on the login screen. It said what domain I was login on. (ad.stockholm.se) But now, it behaves like a private computer. It's like I can't connect to the school domain server. And the login fields won't allow me to use a domain account. As I write this Im on the local admin account. The folder for my school account still exist C:\Users\ab63124. But I can't accses it.
I need help with this, because I gonna hand this in to my school in approximetly 1,5 years. And if it isn't solved by then. Well I don't know.
Edit:
So this is how we managed to create an admin account:
First I called the student support and managed to get the BitLocker key for the harddrive. After reciving it. We unscrewed the laptop and took out the harddrive. Then I plugged it into my other computer and unlocked the harddrive with the BitLocker-key. Now we navigated to system32 folder and searched for sethc.exe. When we found it we removed sethc.exe from the folder and replaced it with another program called sethc.exe but it was actully cmd.exe. So when I then put the harddrive back in place and started the school computer and came to the log-in screen. I pressed SHIFT 5 times, and instead of "Sticky Keys" popping up. Now a command prompt popped up. Now we could create a local admin account on the computer. And that's how it went down.
Update: I now know what I did. I went into System Properites and in the "Computer Name" tab I clicked on "Change" and unchecked Domain. So it went off the network. However, now I tried to change it to my school domain network, but that didn't work I get errorcode: 0x0000232B RCODE_NAME_ERROR it doesn't find the DNS name of the domain. Does that mean I have to change it while Im at school ?
sethc.exe
and the Command Prompt? It would help to format the post so it's not a giant block of text, it may help get you attention/answers.
