Old domain was removed and Unable to login as domain administrator account in windows 7 laptop

1

I have a problem with a laptop that is in an old domain. I need to uninstall some of the programs on that machine. For that, it is asking for the administrator password. The old domain’s administrator account password is not accepted and there is no other local administrator account configured on that machine. How can I log into that machine and join it to the new domain?

If you can gain access to the hard disk (e.g. by connecting it to another system or by booting from a repair disk) it is rather easy to hack into your system.

This article explains how. http://carnal0wnage.attackresearch.com/2012/04/privilege-escalation-via-sticky-keys.html

Once you have a command prompt you can reset the administrator password by using this command:

net user administrator <password>

That is windows 7 laptop, by default the local administrator account is disabled, cant enable that without domain administrator rights. So, I am trying to create a new admin user account on that machine with the help of Hiren's Boot CD, hope it works. – srikanth – 2014-12-02T07:23:03.153

You can enable the local administrator user with the command 'net user administrator /active:yes'. The command prompt that you have after following the instructions will have system rights. – ZEDA-NL – 2014-12-02T10:56:48.103

to do that i need local admin rights at least... – srikanth – 2014-12-02T11:58:16.310

Just try it. It will work. – ZEDA-NL – 2014-12-02T13:18:21.987
