Article: Q186401
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): 
Last Modified: 10-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Performance Monitor analysis reveals a steady increase in private bytes for
Services.exe.

Even more noticeable is the working set for Services.exe - from 10 MB to 400 MB,
depending on up time.


CAUSE
=====

When the server receives a downlevel remoted API, an internal buffer is
allocated related to the session user. For the code path where the API is a
remote user logon, the internal buffer is not freed properly.

RESOLUTION
==========

To resolve this problem, contact Microsoft Technical Support to obtain the
following fix or wait for the next Windows NT service pack.

This fix should have the following time stamp:

  05/26/98  10:07p                88,336 Xactsrv.dll (Intel)
  05/26/98  10:08p               170,768 Xactsrv.dll (Alpha)

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 4.0.

A supported fix is now available, but has not been fully regression tested and
should be applied only to systems experiencing this specific problem. Unless you
are severely impacted by this specific problem, Microsoft recommends that you
wait for the next service pack that contains this fix. Contact Microsoft
Technical Support for more information.
