SharePoint 3.0: How to Crawl Case Sensitive URLs

By default, MOSS will not crawl URLs which are case sensitive. However, Microsoft Help and Support Article ID 932619 provides instructions for making a registry modification to the Index server which allows case sensitive URLs to be crawled.

It is important to note that a content index reset is required. For this reason, this modification may require a maintenance window for production environments, especially large environments with lots of items in the content index that will need to be crawled again.

Like most system changes, it is a good idea to test this first in Development or QA environments, record the change, and then schedule a time to deploy it to production. The instructions are straightforward, however, the first time that I made the modification, the search service didn't start properly so I had to stop it and start it a second time. Then it was fine. Running through the steps in Development or QA first will allow you to work the kinks out.
