Unable to determine the identity of the domain
Hello! I'm working on Reporting Services 2012. I have some report and one problem. This works: - Generation of litle report with web interface and subscribe on Excel with shared folder and email - Generation of big ( request SQL more than 2 min ) report with web interface and subscribe on PDF with shared folder and email But this didn't work: - Generation of big report with subscribe on Excel with shared folder or email I've got this error "System.IO.IsolatedStorage.IsolatedStorageException: Unable to determine the identity of the domain" I try to configure Reporting Services on upgrade DatabaseQueryTimeout 120 => 1800 and I try to share with everyone the folder IsolatedStorage in appData but it didn't works. I use an user Active Directory powerless to subscribe my report but the master of RS is admin of the AD Thanks in advance.

This error has been already covered in at least these three threads: http://social.msdn.microsoft.com/forums/en-US/vsx/thread/a64202cd-23cb-47c4-b92c-88e47354dfc9/ http://rekiwi.blogspot.com/2008/12/unable-to-determine-identity-of-domain.html http://social.msdn.microsoft.com/Forums/en/oxmlsdk/thread/8180ca18-f3db-41df-90e4-63604d2b4021 I trust one of the above has the answer for you.

Hello, Thank for that answer. I looked at this link before but none can help me. The second link is really interesting but my admin Reporting services is the Admin of Active Directory and is admin on the local machine and I can't write some code of AppDomainSetup in Reporting Services.

Hi, From your description, it seems that you are creating subscriptions on a report manager (or SharePoint site) rather than creating the subscription programmatically via Reporting Services Web Service, right? At this time, I suggest that you update the Reporting Services with SQL Server 2012 updates in you test environment. For more information about the SQL Server 2012 builds currently released, please see: http://sqlserverbuilds.blogspot.com/ Regards, Mike Yin

Hi Gatan, Thanks for your posting. By default, ASP .NET places a 4MB limit for the buffering threshold of the input stream by using the maxRequestLength attribute. Maybe the size of the Excel format report exceeds the threshold. At this time, you can increase the maxRequestLength value under httpRuntime in web.config file of Reporting Services. We recommend that you make a backup of each configuration file before you modify it. Then you can refer to the steps below: Navigate to <Drive>:\Program Files\Microsoft SQL Server\MSRS11.[SSRSInstanceName]\Reporting Services\ReportManager, open the Web.config file.Search for httpRuntime, and add maxRequestLength="20000" to the line of code so that the line looks like this: <httpRuntime maxRequestLength="20000" executionTimeout="90000" />Repeat the above steps with the Web.config file in ReportServer folder. (Note: You may need to restart the Reporting Services service after modifying the config files.) If you have any questions, please feel free to let me know. Regards, Mike Yin

Has anyone seen a resolution of this issue? We're in the same boat, and since the SSRS Excel rendering is done inside the MS code base, I can't see a way to apply the code fixes from the chain of articles above. Thanks
