FIX: COM+ Method Calls That Pass an Array of Objects Does Not Complete When You Use Late Binding

If a COM+ component that is configured to run in a server package calls a method on another component in the same package using late binding and then passes an array of collections or an array of objects as a parameter, the method call to the secondary component fails. However, when you use early binding to make the same method call, the call succeeds.

This problem occurs when you use COM+ on Microsoft Windows 2000 and Windows 2000 Service Pack 1.
This problem occurs when COM+ marshalls ByRef SAFEARRAYs that contain interface pointers.
Support has now been added for walking, copying, and freeing ByRef SAFEARRAYs.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 theMicrosoft Knowledge Base:

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 2000 Service Pack 2.
