当前标识没有对“Temporary ASP.NET Files”目录的写入权限

Question

我一直在ASP.NET Web应用程序（如下）中收到此错误。我给网络服务帐户权限指定的文件夹，它运行良好一段时间，但然后在一两天内错误再次出现，因为网络服务帐户已从该文件夹的权限中删除。再次添加它可以修复它，但它为什么保持reocurring？

难道它与使用Interop组件（如WMI）有关吗？

以下是完整的错误：

Answer 1

是您的机器在一个域？这可能是组策略搞乱了它。

在我的情况下，有安全指令禁用ASPNET帐户。

它导致了一个通用的服务不可用错误，需要一段时间才能弄清楚。

我也看看服务器是否安装了思科安全代理（我认为这是名字）。我们遇到了类似的问题，无论我们通过什么方式获得许可，我们都无法将网络服务访问到卷影副本文件夹，结果证明思科安全代理拒绝访问该文件夹。
