Over the weekend I spun up a new virtual machine for a practice TFS 2010 Installation. The TFS installation process is much improved. It can loosely be broken into two phases which are installation and configuration. The installation is the easy part which basically prepares the server and copies some bits to the drive. The configuration is a little more difficult but provides some guidance to help make the important decisions. During the configuration you make the following three key decisions.
- Install WSS 3.0 or use an existing SharePoint installation
- Install SQL Express or use an existing SQL Instance
- Install Reporting Services
During the configuration I received TF255275 Error during the Reporting Services portion of the configuration. My reporting services database was created and configured for SharePoint Mode.
Despite referencing the TFS 2010 Beta the above blog post helped resolve the issue. Essentially, I had to change the database to Native Mode. However, as a commenter mentions I had to delete the Report Database and recreate it in Native Mode before the configuration wizard would complete.
