I've accidentally deleted the System Administrator entry in Directory Utility. How do I recreate it?

How do I recreate the "System Administrator" entry in Directory Utility. It was accidentally deleted.

If you see this article: http://www.stupidlittleblog.com/2011/technology/apple/mac-os-x-lion/mac-os-x-lio n-root-user-sigin-error/#.To_DWOsb6jV
I was having the same root user password login problem.
So I followed the instructions in it, but instead of deleting "AuthenticationAuthority" setting for System Administrator, I accidentally deleted the whole "System Administrator".
Therefore, I'll need to recreate the "System Administrator" entry in the Directory Utility. Maybe you can send me a screen capture of the System Administrator settings so I can try to recreate it. Or else if you know how I can recreate is (maybe from Terminal command line), it will be appreciated.
Thanks.

I accidentally deleted the systems file on my macbook.

In preparation for upgrading from Leopard 5.8 to Snow Leopard I backed up my entire macbook system to an external hard drive. Then I deleted some files prior to installing Snow Leopard but I accidentally deleted the systems files. I can't boot the system now. How do I resolve the situation?

Thanks for the reply.
The backup was via Time Machine.
No, I have not tried booting from the SL 6.0 disc using the c key or Option/alt key. When do I push the option/alt key?

Accidentally deleted the root user from my directory Mac 10.7.5

While trying to disable the root user (because I heard that it should be used sparingly) I think that I deleted it from the directory. Whenever I try a sudo command I get sudo: Command not found. I'm pretty sure this is a problem and some help would be nice.
Thank You!

Back up all data.
Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

Reinstall OS X.
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

HT1926 Everytime I try and install iTunes it says "the system administrator has set policies to prevent this installation". does anyone know what this means?

I am using my partners computer. He has iTunes on his laptop but when I went to update iTunes, it said "the system administrator has set policies to prevent this installation". I therefore deleted iTunes altogether thinking to reinstall the original iTunes and then upgrade it (i,e start from scratch) but to know avail. Is this a problem with my laptop itself? Or a problem with the internet settings?
HELP PLEASE!!

Let's try something relatively simple. Download and save a copy of the installer to your hard drive (don't run the install on line and don't start the install just yet):
http://www.apple.com/itunes/download/
Now right-click on the iTunesSetup.exe (or iTunes64Setup.exe) that you downloaded and select "Run as administrator".
Does that go through any better for you?

I accidentally deleted the documents folder from my hard drive. can I recover it?

I accidentally deleted the documents folder (and its contents) from my ibook hard drive. Can I recover it?

It takes a really expensive data recovery service to get back things that have been deleted.
You could try Data Rescue 3, if you're desperate to get the documents back.
http://www.prosofteng.com/products/data_rescue.php
System Requirements:
http://www.prosofteng.com/products/data_rescue_sysreq.php
If you want to try this, stop using the iBook immediately, and wait until you get the recovery software because every time you save something to your hard drive (even if it's only a link in your browser history), you risk overwriting the files you deleted.

Windows right?
Likely your not the administor any more, the botnet is.
Check on this site really quick if your part of a botnet
http://botnetchecker.com/
All clear? Hopefully. Backup your files to a external drive, cd or dvd, USB keye etc off your computer.
Run the sfx file on this site and it will burn to a cd.
http://www.avira.com/en/support-download-avira-antivir-rescue-system
Next hit your BIO's key and set the cd to boot first, run the scanner and see what it pops up.
If your all clear then create another Admin, transfer your files over from the first Admin.
See if that works, eventually when your totally over to the new Admin, delete the old one.
If you can't create a new Admin, find out who locked your machine down, like your parents or it's a school computer?
Likely installed spyware or "nanyware" to watch you.
Hope that works.

Delete the previous administrator and make a user account for myself on my iMac G4

delete the previous administrator and make a user account for myself on my iMac G4

Open the Accounts pane of System Preferences, create the new account, log in with it, and delete the existing one. If the computer's one you've recently purchased, you may want to erase the drive and install a new OS; do this only if you have the computer's original disks or a retail package compatible with it.

I accidentally deleted the built in Network Utility and need to restore it.

I'm using OS X Mavericks.
I accidentally deleted the built in Network Utility and need to restore it.
It's not in my Time Capsule back ups. Where do I go with this other than an OS reinstallation?

It should be in your TC backup. If not, you will need to Reinstall OS X
Note that with Mavericks, you need to go to: /System/Library/CoreServices/Applications/Network Utility.app
(You can drag to your Dock, or make this an alias)

I have accidentally deleted the trash bin in my mailbox and can no longer move any deleted mail into the trash. I thought I was removing all the emails from the trash but somehow managed to delete the bin instead. Does anyone know who to reinstate it?

I have accidentally deleted the trash bin in my mailbox and can no longer move any deleted mail into the trash. I thought I was removing all the emails from the trash bin but somehow managed to delete the bin instead. Does anyone know who to reinstate the bin?

You are running 10.6.8? If yes, I assume you have your install disks? As the trash bin is part of Mail app and that is an integral part of the OS, the only way I know to get it back is to reinstall the OS. You won't lose any files, just reinstall the OS over the top of the current system.
