APPLIES TO

  • Microsoft Exchange Server 5.5 Service Pack 1



This article was previously published under Q192274


SYMPTOMS

When you create an ActiveX in-process (DLL) component using MAPI, and use it on an Active Server Pages (ASP) with Collaboration Data Objects (CDO), the Internet Information Server (IIS) may terminate unexpectedly if two or more sessions are created by different user accounts.

CAUSE

The Emsmdb32.dll file fails to get global instance for the session when in- process components share the global instance with CDO. This causes the IIS to close.

WORKAROUND

To work around this problem, create the ActiveX component as out-of-process (EXE) or don't use CDO to access Exchange Server.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
