TFS 2013间歇性错误：TF400732：请求已被取消

最近，我们安装了TFS 2013.自安装以来，我们不断收到错误“TF400732：请求已被取消”。 当用浏览器打开TFS或从Visual Studio执行一些任务时。

如果我查看事件日志，我能find的唯一的东西是：

• 修复TFS 2005安装或重新启动
• 使用域凭据访问本地主机上的资源
• 连接到TFS 2010服务器和MS Project 2007版本 – 它是如何工作的？
• TFS 2005 Server从一个硬件恢复到另一个
• TFS 2008：在SharePoint（WSS3）中创build没有项目门户的团队项目 – 如何创build？

重新启动服务器通常可以解决问题，然后在一段时间后重新启动。

有任何想法吗？
