IsolatedStorage初始化失败

我在我的ASP.NET MVC 3应用程序中使用EPPlus 2.8.0.2库来生成excel文件。此应用程序在Windows Server 2003 R2上的IIS 6上运行。IsolatedStorage初始化失败

有问题的行是这样的：

xlsdoc.GetAsByteArray

xlsdoc是一个正确装入ExcelPackage对象。

生成较小的输出是好的，但产生大的输出端产生一个错误：

System.IO.IsolatedStorage.IsolatedStorageException: Initialization failed.

我怀疑EPPlus试图创建使用IsolatedStorage临时文件，但没有写权限IsolatedStorage。我已将应用程序池标识更改为“本地系统”，并且错误消失。

如何在使用'网络服务'身份时避免此错误？

某人blogged about this。他得到了（拒绝访问）错误是从我得到的错误不同，但他的解决方案为我工作：

在C:\Documents and Settings\Default User\Local Settings\Application Data\IsolatedStorage
给写访问给大家该文件夹

提取物：

create folder named IsolatedStorage at the following path "C:\Documents and Settings\Default User\Local Settings\Application Data" and give the permission for IIS_WPG to modify and write. This solves the problem on the windows server 2003
