NTLM v1身份验证只适用于Fiddler2

我今天一直为这个问题烦恼。我一直在开发一个内部应用程序，它可以连续使用HTTP GET和post来填写一系列web表单。当我运行fiddler2(我用来调试GET uri和POST FormData的工具)时，代码工作得很好。现在我没有运行fiddler2，我得到一个身份验证401错误。我想看看标题来比较，但如果不能运行fiddler，这有点困难。

基本上，我的代码通过访问URI和存储cookie来工作。对站点的访问由SSO控制，并且由于服务器运行在2003上，它希望使用NTLMv1。我在Windows 7客户端遇到的第一个问题是，Win7会协商128位，而服务器只会协商64位，身份验证会失败(最终401)。使用fiddler2并将本地机器上的组策略设置为64位，我就能够完成我的工作了。然后我把这个软件变成了一个网络服务，今天发现有一个问题，它失败了。正如我之前所说的，它运行fiddler2都很好，给我留下了一点漏洞，因为我不能让每个客户端安装和使用fiddler2只是为了获得我的功能!

首先是存储cookie....的函数然后我有另一个函数，使用该cookie执行get，第一个函数总是失败，"远程服务器返回一个错误:(401)未经授权。"

我希望在某个地方我错过了一些明显的东西，我不想做一些不可能的事情。

谢谢,艾尔。
