Answer 1

It also seems that changing ApplicationPool's Identity to LocalSystem does not always help which was in my case with Windows Server 2009 R2. The strange thing is that it worked for about half a year since I have read this topic and fixed my problem with large OpenXML-based reports but several days ago it just stopped working.

So after a day of research I found that additionally in ApplicationPool's Advanced Settings set Load User Profile to True (default value was False) and no problems again.

Answer 2

I change application pool Identity to higher level account with full control access in IIS.

IIS> application pools>advanced setting>Identity (in process mode)>choose an account with higher access
