我之前安装了TFS 2013预租，创建团队项目一切正常，工具许可证已过期，只给我一个卸载和重新安装的选项。
我现在安装了tfs 2013的新实例，我创建了一个报表服务器做了所有的配置，测试了网址并且工作正常。但是当我尝试在标准单服务器模式下配置TFS时。我在配置报告时不断收到错误。我是这项技术的新手，但我在第一次安装时没有遇到过这样的问题。报表服务器和tfs都在同一台服务器上。但是我使用的数据库是在名称实例上。
这是我一直得到的错误：
TF255324: The database that you specified cannot be created because a database already exists with that name. The database name is: Tfs_Warehouse. The server hosting the database is: URANUS\dev. You can use one of the three following options.
• If the database is a valid database from a previous version of Team Foundation Server and you want to upgrade it, you must use the Upgrade from Previous Version Wizard.
• If the database is a valid database from the current version of Team Foundation Server and you want to use it, you must use the Application Tier Only Wizard.
• If the database is a valid database used by another Team Foundation Server instance and you wish to create a new database, you must use the advanced wizard to supply a different SQL Server instance or database label.
有关详细信息，请参阅自述文件和Team Foundation的安装指南。

You can manually delete or rename this database before you continue, but it is not required. If you do not, the database will be renamed as part of the installation process.
TF400080: Your system does not have the recommended amount of system memory available: 10 GB. While SharePoint 2013 with Team Foundation Server can operate with less than this amount of memory, the performance will be degraded. Upgrade your system memory to at least the recommended minimum for optimal performance.
TF255142: Windows Firewall is not enabled. If you enable Windows Firewall after configuring Team Foundation Server, you must add exceptions for ports used by Team Foundation Server to Windows Firewall.
