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
To resolve this problem, obtain the latest service pack for Windows NT 4.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0. This problem was first corrected in Windows NT 4.0 Service Pack 5.
