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: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

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\NoteTypes\{476E6449-AAFF-11D)-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.
