So just guesses or comments.
I noticed your command prompt path was from Windows\System32. Did you try that from the root directory, ie; C;\>
As I understand it, it shouldn't make any difference, but since that failed with this machine, try anything?
Does this Administrator account display with just C:\net user ?
There is a lot of chat about this in the HowToGeek link below. it may be worth sifting through all that for clues.;
Where are you with this system now? Does it have an Admin capable User account that is working? If so I would create that 2nd Admin capable account anyway, as a precaution.
I see that someone else had this 1359 error when attempting to do the same in the forum discussion here;
Perhaps that will give some clues.
Sorry, a bit meagre from me.
I am trying to resolve an issue with another persons Compaq Presario V6000 laptop running Vista Home Premium. The original issue was that he forgot his user password and was locked out at the welcome screen. There was no other account visible. I was able to download and burn a bootable (evil Linux created) password reset disk, find his username and clear the PW. The system booted fine after that. Thinking the administrator account might have a blank password, I pursued that idea, but found no account visible. I used the elevated command prompt screen attempting to enable the hidden account which is, BTW,
C:\Windows\system32\net user administrator /active:yes
Having tried this from normal login, safe mode and safe mode with command prompt several times, I've had no success. I'm sure I have the command and syntax correct but it returns the following:
System error 1359 has occurred.
An internal error occurred.
Upon web research, this seems to be a rather generic error without much help available.
I want there to be two admin accounts and, while I could just create a second one, it bothers me that I cannot enable the hidden account. I'm not that familiar with Vista, however. The PW reset disk did show the existence of an "administrator" account in the registry. Any thoughts? TIA
