256986 Description of the Microsoft Windows Registry



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: 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 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.
