SYMPTOMS
A queued component that is installed as an event class may cause an access violation after you install the following rollup hotfix:

When this occurs, you may see the following error message:

An error occurred while processing the last operation. Error code 80080005 - Server execution failed The event log may contain additional troubleshooting information.

Or, the event log may contain the following entry with COM+ as the source:
