SYMPTOMS
When an application uses the Managed Provider for Host Files in Microsoft Host Integration Server 2006 to access an IBM mainframe or an iSeries (AS/400) computer, you receive an access denied error message. This problem occurs when a user account that does not have administrative credentials tries to start the application.



CAUSE
This problem occurs when the Managed Provider for Host files tries to start the SNA Distributed Data Management (DDM) service (Ddmserv.exe) after the application initializes the Managed Provider for Host Files. Because administrative credentials are required to start a Windows service, an access denied error message is returned when an account that does not have administrative credentials tries to start the service.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
After you apply this update, the Managed Provider for Host Files does not try to restart the SNA DDM service if the service is already running. If the SNA DDM service is not running and the application that calls the Managed Provider for Host Files is started without administrative credentials, the application will receive an error that indicates that the SNA DDM service is not started instead of an access denied error.
