Enable local administrator account on Windows Server 2008 R2 Standard

Hi,
I've made a bit of a boo-boo and disabled the local (built-in) administrator account.  This is on a single server installation of Windows Server 2008 R2 Standard edition.  The server is standalone at the moment and not joined to any domain.  

I was required to create some named user accounts that were supposed to be added to the administrators group, but mistakenly disabled the local administrator account before doing this.  Is there a way I can re-enable the local administrator account or will I need to rebuild the whole server again?

Thanks

Personally, I would reinstall Server 2008 and learn from the experience. There are bootable CDs that you can find online that allow you to edit the registry but I have only used these in Windows 2003. Problem is you simply don't know what other changes these disks do.

Whenever I am configuring a server I ALWAYS create a backup admin account before doing anything because like you, I have forgotten or disabled the admin account in the past.

I hope someone finds you an easier solution.

If any of the accounts you created are part of the local admin group then log on with one of those and enable the admin account.

that's the thing...the accounts I created were mistakenly never added to the local admin group and i've gone ahead and disabled the built in administrator account.

Hi!

Try this tool:
http://pogostick.net/~pnh/ntpasswd/

I haven't used it on W2K8 servers yet, but it has worked on Vista and Windows 7. You can reset local administrator's password and enable account at the same time.

Thanks everyone.  I've resorted to rebuilding the servers, which shouldn't take long, since there wasn't much on there in the first place.  

Was a little unsure of the tool, since it hadn't been tested on Win Server 2008 and because the server will be used to host a critical system, so i'm a little weary of using it to make changes to the registry.  Will definitely prove useful if I have to deal with any future vista or windows 7 build, so thanks!
