SYMPTOMS
When you are using a Lightweight Directory Access Protocol (LDAP) control to gain access to the Windows 2000 Active Directory, the control causes the server to shut down because of an access violation. The following error message appears before the shutdown:

The system process lsass.exe terminated unexpectedly with status code -1073741819. The system will now shut down and restart.

The event log records the following Directory Service event:

Event ID: 1173

Internal event: Exception c0000005 has occurred with parameters 77952c23 and ) (Internal ID 0).



CAUSE
This behavior occurs because, if an LDAP control sends an octet string whose length field indicates that the octet string is longer than the number of bytes in the buffer, LDAP does not validate the length correctly and an access violation occurs.



RESOLUTION
