当我运行调用UserPrincipal.GetGroups的简单控制台应用程序时，它会枚举用户组，没有任何问题。但是，当我在同一台服务器上运行与同一用户相同的代码但从托管WCF的Windows服务运行时，我得到以下错误链：
Message : The socket transfer timed out after 00:00:10. You have exceeded the timeout set on your binding. The time allotted to this operation may have been a portion of a longer timeout.
Inner Exception
---------------
Message : The read operation failed, see inner exception.

Message : A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
这可能与WCF线程模拟有关吗？ WindowsIdentity.GetCurrent().Name返回相同的用户，但是Thread.CurrentPrincipal.Identity.Name是不同的 - 在控制台应用程序的情况下是空字符串，但在Windoes服务的情况下是模拟的WCF用户。
