Windows 7 Unable to login as local adminstrator is disabled and no other accounts are there on system

Hi All,

Situation is somehow local admin account got deleted which was created during the time of installation using domain admin account. Later we were unable to login to that machine using the local administrator account as its disabled. Even we are unable to login to machine using domain admin or any other local account.

Awaiting for reply. Please reply ASAP

Thanks a tonne! :)

Thanks Tolomir, nimatjic and abbright for your comments :)

Here is what happened all the way :)

1. Windows 7 machine had two local administrator accounts and it was in domain along with domain user to which we had granted local admin access on that machine.
   -> Default administrator(Which was disabled/hidden by default)
   -> One more local account which was created during the OS installation which will have administrator privileges.

2. In domain user login who had admin access on that machine deleted the local login which was created during the time of installation and didn't logout from his machine which let him work for long time without any issues till the time he was in.

3. Some how the computer Account was deleted from the Domain which led to all these problem where even after enabling the Administrator account we were unable to login(I don't more about this why the administrator account was not working).
4. But I found a solution after lot of R & D and got an idea of adding the same computer name of  the machine on the domain and then restarted system. which let me login to machine after enabling administrator account:)

It was interesting though but found a solution. :)

I know its little confusing but interesting issue which i never comes across. ;-)

Tolomir:
I guess your Solution works only if I login/get into the computer but the thing was like I was not able to login at all.

nimatejic:
I had already tried all the steps from the command mode, but didn't worked. Issue was kind of different which took long time to resolve. :)

Thanks again for comments!

Hope we get lot of things to learn. :)

Best,

When you install windows 7, you enter an account name. This is always a local account name.

It is right that the administrator account is disabled by default. you can enable it with this tutorial: http://blog.eches.net/how-to-enable-windows-7-hidden-administrator-account/

What was changed so that you can no longer login to that computer?

Try booting from your DVD and enabling the built-in Administrator account that is disabled by default.

Choose to"Repair your computer".
Choose "Command Prompt". Now type the following:

net user administrator /active:yes [press Enter]
net user administrator password 11223344 [enter]

Once you enable the Administrator account, you will see an icon for Admin account on the Welcome Screen when you reboot and can get into it with the password 11223344.

You may want to try to boot to protected mode (press F8 during boot) and try logging in as local administrator. If I remember correctly this account is automatically enabled when there's no other administrative account available.
