Isolated Storage Exception: Unable to determine the identity of domain

问题

I setup a subscription in a SQL Server 2012 SP1 Reporting Services instance that exports a 34MB file to the Excel 2007-2013 XLSX OpenXML render extension. The subscription throws the following error:

System.IO.IsolatedStorage.IsolatedStorageException: Unable to determine the identity of domain.

I verified it is possible to export the report from Report Manager to the Excel 2007-2013 XLSX OpenXML render extension without a problem. This error only occurs when the report is executed via a subscription. I have researched this and found the following recommendations on the web:

Two separate Microsoft Connect bug reports 764356 and 764556 that have no listed work arounds.
A recommendation to stagger the subscriptions so that only one runs at a time. This does not help since only one subscription is running at the time of the error.
A recommendation to use the Excel 2003 render method and break the rows into separate tabs to avoid the 65,536 row limit. I did verify this works, but this was not an acceptable solution from the business stakeholder's perspective.
A comment indicating any report using the Excel 2007-2013 render method that exceeds 10 MB in size switches from being generated in memory to using Isolated Storage. There's no explanation why this is bad and I assume this was done for a good reason -- perhaps to limit RAM consumption.
A suggestion to elevate permissions for users in the Isolated Storage folder for the ASP.NET application. I could not find where the Isolated Storage folder is located for Reporting Services.
A suggestion to wrap the ASP.NET's code for Isolated Storage with extra code that by-passes this problem. I couldn't find a way to apply this solution to Reporting Services since this is a shipped product from Microsoft.
A suggestion to modify the Report Manager and Report Server web.config files to include maxRequestLength="200000" in the httpRuntime node. This did not change the results.
A suggestion to increase memory settings explicitly in RSReportServer.config. This didn't seem like it would help since the error relates to Isolated Storage, but I tried it out of desparation. This did not change the results.
A suggestion to change the DatabaseQueryTimeout value from 120 to something larger. This did not change the results.
A suggestion to change the Subscription execution timeout value. This did not change the results.

Below is a copy of the full error log entry:

You can find a solution here: http://rekiwi.blogspot.com/2008/12/unable-to-determine-identity-of-domain.html

In the COM component, create a new AppDomain with the appropriate evidence and execute the code in that.

Here is a code example that fixed the problem for me:

AppDomainSetup setup = new AppDomainSetup();
setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory.ToString();

//Then we need our evidence
System.Security.Policy.Evidence evidence = new System.Security.Policy.Evidence();
evidence.AddHost(new System.Security.Policy.Zone(System.Security.SecurityZone.MyComputer));

//Now we can fire up an AppDomain running with that evidence.
AppDomain domain = AppDomain.CreateDomain("YourDll.YourClass", evidence, setup);

YourDll.YourClass yourclass = (YourDll.YourClass)domain.CreateInstanceAndUnwrap(typeof(YourDll.YourClass).Assembly.FullName, typeof(YourDll.YourClass).FullName);

yourclass.CallYourMethod();

Any types you want to marshall across AppDomains have to marked [Serializable()] and must inherit from MarshalByRefObject. For example:

namespace YourDll
{
[Serializable()]
public class YourClass: MarshalByRefObject
{
...
