WSS Search: Cannot be crawled

After reviewing our Application log for our SharePoint server I noticed the following entry:

Event Type: Warning

Event Source: Windows SharePoint Services 3 Search

Event Category: Gatherer

Event ID: 2436

Description: The start address sts3://server:port/contentdbid={GUID} cannot be crawled.

Solution:

Some of the web applications didn't have a site collection on the default root sites. To check this browse to your web applications e.g. http://server:port. If you receive a HTTP 404 error you'll have to create a site collection for the web application.

To create a site collection browse to SharePoint Central Administration > Application Management > Create Site Collection and create a Blank team site for the appropriate web application.

This should sort out the consistent warnings in the event log.
