FIX: Extended Error Information Is Lost When Calling In-Process Neutral Thread Model Components (269479)



The information in this article applies to:

  • Microsoft Windows 2000 Server SP1
  • Microsoft Windows 2000 Advanced Server SP1
  • Microsoft Windows 2000 Professional SP1

This article was previously published under Q269479

SYMPTOMS

When you run a Microsoft Visual Basic client, the Err.Description property has a value of 'Method "~" of object "~" failed' after a call to an in-process Neutral Thread Model object that supports extended error information fails.

When you run a Microsoft Visual C or C++ client, a call to GetErrorInfo to retrieve extended error information from an in-process Neutral Thread Model object returns S_FALSE after a call to IUnknown is made on the object.

CAUSE

This problem occurs because standard Component Object Model (COM) proxy-stub implementation clears extended error information that is associated with the logical thread when a call is made to a Neutral Thread Model object through the IUnknown interface.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
