IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS

You may find multiple instances of the following entry in the Directory Services event log:

Event Type: Warning
Event Source: NTDS LDAP
Event Category: LDAP Interface
Event ID: 1216
Date: 11/19/2000
Time: 9:12:58 PM
User: N/A
Computer: Computer
Description:
The LDAP server closed a socket to a client because of an error condition, 1234. (Internal ID c01028c::4294967295).

Note that the Internal ID value varies with each instance.

CAUSE

This event log message occurs when a Lightweight Directory Access Protocol (LDAP) client sends a request to the computer by using User Datagram Protocol (UDP) but does not keep its socket open to listen for the response from the server. When the server tries to send the answer back, the error message is logged to the event log. This is a harmless error that can occur frequently under normal operating conditions. It occurs only if the diagnostic logging level is increased by modifying the level of LDAP logging to 2 or above in the registry.

RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To resolve this issue:

Start Registry Editor (Regedt32.exe).

Locate the LDAP Interface Events value in the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Diagnostics

Set the data value of the LDAP Interface Events value to a lower setting, and then click OK.

Quit Registry Editor.

The default value for this registry value is 0.
