今日服务异常器抛一怪异问题。在Xml序列化时提示：FileNotFoundException, Could not find file 'C:\WINDOWS\TEMP\wpbzwlwo.dll'.

经网上查阅，原来这是个服务器执行权限问题。站点进程由inetinfo.exe以管理员权限创建， w3wp启动时会附加这个站点(window station)运行，但它不是一个Console process，当子进程csc.exe开始处理请求时，会使用默认的window station Service-0x0-luid$ 重新创建Console information ，导致运行权限不足。

因此，可以通过配置应用程序池标识设置管理员组来解决这个问题。
