SYMPTOMS
The time-out mechanism for Lightweight Directory Access Protocol (LDAP) may not work, causing old connections to remain connected. As a result, hundreds of stale LDAP connections may exist on a computer. Although this does not prevent LDAP connections to the server, the stale connections may continue to use system resources until you reboot the server.



CAUSE
The scheduler thread that determines when to time out LDAP connections does not correctly handle the rollover of the 32-bit time value returned by the GetTickCount function. When a rollover occurs, the server stops timing out inactive connections.



RESOLUTION
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 the Microsoft Knowledge Base:

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 Windows 2000 Service Pack 1.
