FIX: MSMQ: GetStreamedObject and GetStoredObject Return Error with VT_UNKNOWN (241755)

The information in this article applies to:

Microsoft Windows NT Server 4.0 Terminal Server Edition
Microsoft Message Queue Server (MSMQ) 1.0

This article was previously published under Q241755

SYMPTOMS

Sending components that result in calls to either GetStreamedObject or GetStoredObject receive errors with incorrect HRESULT values.

CAUSE

MSMQ passes VT_UNKNOWN in the variant's type tag after a call to query interface. This is valid. The HRESULT should have been reset prior to returning, but it was not. This resulted in errors due to the HRESULT being set incorrectly.

RESOLUTION

Windows NT Server 4.0, Terminal Server Edition

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

Passing VT_UNKNOWN is by design and the code was corrected to reset the HRESULT to NOERROR.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Windows NT Server version 4.0, Terminal Server Edition Service Pack 6.
