After installing an SBS 2008 Update Rollup (2 or higher) you might see the following event in the application event log happening very 5 to 10 minutes.”The update cannot be started because the content sources cannot be accessed. Fix the errors and try the update again.” New content’ll not be added to the search index and in consequence it’ll not be found when doing a full text search within the CompanyWeb application. To resolve, follow the resolution presented in this post, you’ll need to add the host name that you created using the Internet Address Management Wizard for public access, it’ll usually be in the form “Remote.Contoso.com”, If you’re not sure on what URL to use, you can look for the event id 2436 as mentioned in the post.
