SYMPTOMS

Consider the following scenario:
  • You use a DCOM program that consists of a client computer-side program and a server-side program.
  • You install the server-side program on a Microsoft Windows XP-based or a Microsoft Windows Server 2003-based computer.
  • The DCOM program uses Connect level security that is set by using the Dcomcnfg.exe utility.
  • You run the client computer-side program against the server-side program.
In this scenario, a memory leak occurs in the Lsass.exe process on the server. You have to restart the server when this problem occurs.

CAUSE

This problem occurs because of a memory leak in the negotiate security package.
