While setting up Microsoft Team Foundation Server 2010 Beta 2 one might into an non obvious issue with user rights. The error observed would look the following:

The  TFS installation considered is a single machine installation with SQL Server Reporting and Analysis services and SharePoint Services installed during the TFS installation.

The full descriptions of the error is:

Error
TF30224: Failed to retrieve projects from the report server. Please check that the SQL Server Reporting Services Web and Windows services are running and you have sufficient privileges for creating a project.

Explanation
The Project Creation Wizard encountered a problem while creating reports on the SQL Server Reporting Services on http://coruscant/ReportServer/ReportService2005.asmx. The reason for the failure cannot be determined at this time. Because the operation failed, the wizard was not able to finish creating the SQL Server Reporting Services site.

User Action
Contact the administrator for the SQL Server Reporting Services on http://coruscant/ReportServer/ReportService2005.asmx to confirm that the SQL Server Reporting Services server is running and you have sufficient privileges to create a project . Your user account on SQL Server Reporting Services must have Content Manager permission to create a new project. Also, you might find additional helpful information in the project creation log. The log shows each action taken by the wizard at the time of the failure and may include additional details about the error.

A wild guess might be checking all rights for SQL Server, SharePoint sites, SQL Server Reporting Services etc. Pat Ramadass comes up with the right hint that origins from the previous TFS version.

First of all do not look for the Reporting Service Configuration Manager. Go straight to http://localhost/Reports/ (logged in on your TFS server machine with administrator rights). You will get the SQL Server Reporting Services site. Select the Properties page and click on New Role Assignment.

Now add exactly the user (or group) you tried creating the TFS Team Project with. Select at least Content Manager and confirm by pressing OK.

Go back to you local machine and try to create the TFS Team Project again. The users should now have sufficient rights to create the project.
