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.

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.
