Symptoms

When a program that is running in Windows 95 or Windows 98 attempts to connect to a Microsoft Windows NT-based or Microsoft Windows 2000-based server by using Windows NT LAN Manager (NTLM) security services and prompts you for credentials (your user name and password), the connection attempt may sometimes not succeed.

Cause

If your user name and password are passed by the program to the NTLM Security Support Provider interface (SSPI) in the form of Unicode strings, the credentials may not be successfully created.

Directory Service Client conflict information

The hotfix that is described in this article is not fully compatible with the Windows 95 or Windows 98 Directory Service client. The Windows 95 and Windows 98 Directory Service client contains a version of the Secur32.dll file that provides additional functionality that is not included in the version of the Secur32.dll file that is included with Windows 95, Windows 98, and Windows 98 Second Edition. This hotfix also does not provide the additional Directory Service client functionality. Therefore, the order in which you install this hotfix relative to the Directory Service client is critical. You must install this hotfix after you install the Directory Service client is installed. If you install the Directory Service client after you install this hotfix, you must then reinstall the hotfix. This is necessary because of the behavior of the Directory Service client installation program.
