FIX: IsWorldReadable and MSMQ Window Handle Leaks

ID: Q241771

The information in this article applies to:

Microsoft Message Queue Server version 1.0

SYMPTOMS

Window handle leaks are seen when applications create queues with the option IsWorldReadable set to True. This only occurs with Windows NT computers. Security differences on Windows 95 and 98 do not support the creation of queues with IsWorldReadable set to True.

CAUSE

This occurs in GetCurrentUserSid because the Open (Thread/Process) Token call was not paired with a CloseHandle call.

RESOLUTION

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

Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack

This problem has been corrected in Windows NT 4.0 SP6 with the addition of CloseHandle calls to match Open (Thread/Process) Token calls.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

This problem was first corrected in Windows NT 4.0 Service Pack 6.
