After you install Service Pack 1 on a computer that runs Windows 2000 with Microsoft Exchange 2000 Server, Exchange 2000 Server may not run correctly. This behavior occurs only when you reregister (reinstall) the Aqueue.dll file.
This behavior can occur because the Aqueue.dll file does not register for all of the class IDs (CLSID). Specifically, it does not register the Phatq.dll for Exchange 2000 Server. The effect is that the Exchange Server restriction checking code uses the wrong .dll file. The restriction checking does not have the correct configuration information and does not become bound to the metabase. This also causes a memory leak when you shut down the computer.
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:

Microsoft has confirmed that this is a problem in Microsoft Windows 2000. This problem was first corrected in Windows 2000 Service Pack 2.
