OL2000: Password Expires with No Prompt to Change Password

If you are logged on to the network and your password expires, when you try to start Outlook 2000, many event ID 535 messages may be generated and logged in the server Security log.

In Outlook 2000, the User Credential dialog box in which you can change your password may not be displayed; instead, a Network Error dialog box is displayed.

This problem can occur if the Microsoft Exchange Server address provider state computer does not handle the invalid user credentials correctly.

To resolve this problem, obtain the latest service pack for Microsoft Office 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base: To enable the users to change the password, you must enable the registry entry, later in this article, on the Primary Domain Controller.

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 enable this fix, modify the following registry entry on the domain controller:

1. Start Registry Editor (Regedt32.exe).
2. Locate the following key in the registry:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. On the Edit menu, click Add Value, and then add the following value:
   Value Name: TCPIPClientSupport
   Data Type: REG_DWORD
   Value: 0x0, 0x1
   Default: 0x0 (not in registry by default)
   Description: Enable LSA to have a NCACN_IP_TCP end point registered
4. Click OK, and then quit Registry Editor.
5. Quit and restart the primary domain controller.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

After you apply the fix, you may notice a reduction in the Event ID 535 on the server security log. You may also notice that Outlook 2000 now displays User Credential dialog box; however, the user may be unable to change the password.
