What to do if you get MOSS 2007 COM/W3SVC-WP 80070005 Errors

I recently installed a MOSS 2007 server and applied several service packs, including WSS SP1 and MOSS 2007 SP1. This resulted in COM+ application security settings being reset to their default settings, specifically the COM+ application, OSearch.

The event viewer revealed the following error, for me:

The Execute method of job definition Microsoft.Office.Server.Search.Administration.IndexingScheduleJobDefinition (ID 86e55a13-e654-4458-aa3c-87f910d6ec9e) threw an exception. More information is included below. Retrieving the COM class factory for component with CLSID {3D42CCB1-4665-4620-92A3-478F47389230} failed due to the following error: 80070005.

Other associated errors produced by this problemare shown below and can be resolved by the following steps:

Starting up database 'SharedServices1_Search_DB_GUID'.

The worker process failed to initialize the http.sys communication or the w3svc communication layer and therefore could not be started. The data field contains the error number.

Unable to reach Excel Calculation Services http://HOSTNAME:PORT/SharedServicesProvider/ExcelCalculationServer/ExcelService.asmx.
