SYMPTOMS
You may experience increased latency in your custom Microsoft COM+ application each time that a .NET object is created on a Microsoft Windows 2000-based computer with the Microsoft .NET Framework 1.0.



CAUSE
This problem occurs when a client COM application creates a new .NET object. The Mscorwks.dll file stores the .NET Framework object in the hash table with the CLSID as the key. During lookup, the Mscorwks.dll file passes a different GUID. This behavior creates a new entry in the hash table. Therefore, the hash table size increases every time a client COM application creates a new .NET object.



RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next .NET Framework service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:
