SYMPTOMS
When you remove the Domain Name Service (DNS) service from a computer running Windows 2000 Server, the snap-in for DNS management is not removed from the Computer Management Microsoft Management Console (MMC).

After you remove the DNS service, you may receive the following error message when attempting to expand the "Services and Applications" tree from the Computer Management MMC:

Snap-in failed to initialize.

Name: - not available -

CLSID: {80105023-50B1-11D1-B930-00A0C9A06D2D}



CAUSE
This behavior occurs when there is an orphaned entry in the registry.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, remove the orphaned registry entry:  Start Registry Editor (Regedit.exe). Locate the {80105023-50B1-11D1-B930-00A0C9A06D2D} value under the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\NodeTypes\{476E6449-AAFF-11D0)-B944-00C04FD8D5B0}\Extensions\NameSpace

 Click the value in the right-hand pane, and then press DELETE. You are prompted to verify the deletion of the key. Be sure the Data portion of this key pertains to DNS. If so, you have the correct key. Click Yes to delete the key. Quit Registry Editor.</ol>
