<div class="resolution_section">

RESOLUTION
To resolve this problem, obtain the latest service pack for Internet Explorer 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

276369 How to Obtain the Latest Service Pack for Internet Explorer 5.5

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.

Verify the following information:
 Verify that the version of the Activeds.tlb file is correct for the version of Windows 2000 you are using. The version number should be at least 5.0.2143.1. The Activeds.tlb and Activeds.dll version numbers may not necessarily match.</li> View the following key in the registry:

HKEY_CLASSES_ROOT\CLSID\{080d0d78-f421-11d0-a36e-00c04fb950dc}

This key should be the Active Directory's Pathname object. It should contain a key named TypeLib that should have the a value of {97d25db0-0363-11cf-abc4-02608c9e7553}.</li> View the following key in the registry:

HKEY_CLASSES_ROOT\TypeLib\{97d25db0-0363-11cf-abc4-02608c9e7553}

This key should contain a key named 1.0 that has three more keys:  0</li> Flags</li> HelpDir</li></ul>

The 0 key should have a subkey named win32 that should have a value that points to %SystemRoot%\System32\Activeds.tlb.</li></ul>

Verify that the following registry key exists:
HKEY_CLASSES_ROOT\LDAP\Clsid

If this key does not exist, follow these steps: <ol> Run Notepad.exe.</li> Cut and paste the following text into Notepad:

<pre class="fixed_text">Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\LDAP\Clsid] @=&quot;{228D9A81-C302-11cf-9AA4-00AA004A5691}&quot;

</li> Save the file as Ldap.reg.</li> Double-click on the file to import the registry setting in to the registry.</li> Verify HKEY_CLASSES_ROOT\LDAP\Clsid exists, and that it has a CLSID of 228D9A81-C302-11cf-9AA4-00AA004A5691.</li></ol>

<div class="status_section">

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Internet Explorer 5.5 Service Pack 2. However, Internet Explorer 5.5 SP2 may not address the issue in all cases and you may still need to add the LDAP registry manually.
