我一直在我的ASP.NET网络应用程序中收到此错误（如下）。我将网络服务帐户权限授予指定文件夹，它运行正常一段时间，但随后在一两天内再次出现错误，因为网络服务帐户已从文件夹的权限中删除。再次添加它会修复它，但为什么它会继续重复？
是否与使用Interop组件（如WMI）有关？
这是完整的错误：

您的计算机是否在域中？这可能是团体政策搞乱了。
在我的情况下，有安全指令禁用ASPNET帐户。
它导致了一般服务不可用错误，需要一段时间才能搞清楚。

我还想查看服务器是否安装了思科安全代理（我认为这就是名称）。我们遇到了类似的问题，无论我们做了什么许可，我们都无法获得对阴影副本文件夹的网络服务访问权限，结果证明是思科安全代理拒绝访问该文件夹。
