An SNA application may start very slowly on a Host Integration Server 2000 End-User Client (836504)



The information in this article applies to:

  • Microsoft Host Integration Server 2000
  • Microsoft Host Integration Server 2000 SP1

SYMPTOMS

When you try to start a Microsoft SNA Server application on a Microsoft Host Integration Server 2000 End-User Client, the SNA application may start very slowly.

CAUSE

This problem only occurs if two applications that have different permissions are running on the same computer, and if one of those applications is implemented as a service. The second application fails with an "Access Denied" error message when the application tries to open a certain event, and then the application waits for 10 seconds before it retries.

WORKAROUND

To work around this problem, use one of the following methods:
  • Use the Host Integration Server 2000 Administrator Client, and configure SnaBase to run as a service.
  • Configure your SNA application to run as an executable file, instead of as a service.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

This problem was corrected in Microsoft Host Integration Server 2000 Service Pack 2.

MORE INFORMATION

When an application is started, it creates an event named MSHostIntegrationServer_UserHiveUpdated by using the default security descriptor. If a second application tries to open this event by using its security descriptor, the application fails. After you apply this hotfix, the MSHostIntegrationServer_UserHiveUpdated event has Everyone access.
