When you attempt to establish a Secure Sockets Layer (SSL) connection for Lightweight Directory Access Protocol (LDAP) with ADSI 2.5 on Windows NT 4.0, you may encounter an access violation (AV) in Wldap32.dll.
The interface for software to utilize SSL changed between Windows NT 4.0 and Microsoft Windows 2000. With Internet Explorer 5.5 on the computer, the Windows 2000 interfaces are used, and these are initialized differently than those that originally were available to Windows NT 4.0. This can lead to situations where unexpected data are passed around, causing this access violation.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
