Active Directory Users and Computers Error: Naming Information Cannot Be Located

Asked By Alllan 200 points N/A Posted on - 06/22/2011

Hello people,

I have installed Windows Server 2008 standard edition PC on a workstation in my laboratory. The current domain is managed by two servers running 2003 Active Directory (AD) Setup. Before installing my Windows Server 2008 computer, had upgraded my AD settings to be compatible with AD 2008. The installation was fairly easy and went smoothly. I have had no problems in the installation process.

Later after you have installed, it made several changes, and then apply windows updates which prompted me to reboot I did. It is when the problem started. Following error after you restart the server and open the administrative tool Active Directory users and computers:

Active Directory Domain Services

Naming information cannot be located because:

The RPC server is unavailable.

Contact your system administrator to verify that your domain is properly configured and is currently online.

And whatever does not go ahead. I restarted the server and then went into safe mode to see if things are well and working. In safe mode, there is no problem. But when you restart normally, it gives me the same error. Anyone with an idea on the subject please can help me out.

Thank you.

Active Directory Users and Computers Error: Naming Information Cannot Be Located

Hi Allan!

Wow, this is really a serious problem. But don't worry, every problem has a solution. Here's a simple and basic way to solve it. Just follow the steps. We're going to do a system restore. Too bad you didn't specify your Windows OS. Don't worry this will not affect your personal files such as emails, documents or photos but the changes that you made and the windows update will be removed. You can still make those changes after the system restore.

For Windows XP:

1. Log on as an administrator.

2. Click START > Accessories > System Tools > System Restore

3. Welcome to System Restore screen appears. Select Restore my computer to an earlier time.

4. Select a Restore point. (I bet you still remember the date you installed the windows update to your computer.

5. Click NEXT

6. Restart your computer.

7. Log on to the computer as an Administrator.

8. Click OK on the System Restore Restoration Complete page

Check if your computer will perform as expected. If not, you can always undo the restoration.

Hi there user:

You just mentioned that you made ‘several’ changes while on progress. There could be one (1) changed of settings that destroy all. Aside from restoring your settings, I’m sure you have in your mind what are those changes you’ve made. There could be one (1) or two (2) clicks or checks that brought you to this. Try to set it again, and if the dialogue box still appears, then surely you will need to restore. That’s the last thing you will do.

Thanks for asking.
