问一个WindowsIdentity的异常问题,求救!!!

[aqbeyond]

各位好,现在将以前的系统的SESSION改为保存到SQL数据库中,很多地方都改了,但是就是画面访问的时候,出现一个WindowsIdentity的异常问题.
异常的基本意思是:System.NotSupportedException: WindowsIdentity Object在访问的时候,不能进行串行化(Serial)处理.
而在这个系统中就没有用到WindowsIdentity类,本人对WindowsIdentity类的使用也不甚了解,因为时间紧,而且也找了很多资料没有结果,特此请教各位,谢谢先!

画面就抛这样的异常提示信息,这个异常时不时时候产生,搞不清楚,也没DEBUG出哪些代码出错,茫然中...
