Q165483: RasEnumEntries() API Leaks Memory

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

- Microsoft Windows NT Workstation versions 3.51, 4.0 
- Microsoft Windows NT Server versions 3.51, 4.0 
-------------------------------------------------------------------------------


SYMPTOMS
========

When an application repeatedly calls the RasEnumEntries() API, system
performance slows down and disk activity increases.

CAUSE
=====

The Win32 API RasEnumEntries() does not deallocate all of the memory it needs to
process the phonebook. Any process repeatedly calling this API continues to
grow. The amount of memory lost is related to the size of the phonebook and the
frequency in which RasEnumEntries() is called. When the application terminates,
all memory is released to the system.


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are
researching this problem and will post additional information here in the
Microsoft Knowledge Base as it becomes available.

Microsoft has confirmed this to be a problem in Windows NT version 4.0. This
problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack.
