今天一个团队成员在创建团队项目时遇到这个问题：
Error
Insufficient permissions on the Windows SharePoint Services at 123.12.15.25 to create a new site.
Explanation
The permissions granted your user name and ID on the Windows SharePoint Services at 123.12.15.25 do not allow you create a new portal site.You must be granted specific root permission by the server administrator.
User Action
Contact the administrator for the Windows SharePoint Services at 123.12.15.25 and ask that the permission “Administrator” be added to your user account.
我发现我已经为他分配了Team Group Member权限、PortalSite访问权限、Sql Reporting Services访问权限，后面才知道，要创建一个Team Project，还需要有Windows Sharepoint Services权限，具体解决方法如下：
1、在Team Explorer中右键点击tfs服务器，然后选择“组成员资格”：
2、在下面的窗口中点击“Windows SharePoint Services 中心管理”：
3、在管理中心站点中，选择网站操作下的网站设置：
4、在下图中，选择人员和组：
5、选择新建->添加用户:
6、输入用户的AD用户名，点击确定即可。
