Symptoms

When a COM server object is registered as single use and is also using the single threaded apartment model, attempts by a client to create a new instance may get delayed.

Cause

Windows 2000 sends a create instance request to a previously created instance of the server, even though it was created as single use. If the server is busy (out of its message loop) it could cause a delay.

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:
