SYMPTOMS
========

When you repeatedly change the private properties of the Server Message Block
(SMB) share resource (ones that are exposed with "cluster res fileshare /priv"),
heap corruption may occur. This may also cause an access violation error message
to be displayed.

CAUSE
=====

This corruption occurs because the address passed to ResUtilFreeParamaterBlock
is invalid, and this address is eventually passed to LocalFree, causing the
access violation.

RESOLUTION
==========

additional information, please see the following article in the Microsoft
Knowledge Base:

STATUS

first corrected in Windows NT 4.0 Service Pack 5.
