401 Unauthorized access Error in SSRS

In the SSRS Reporting Environment, you may never encounter this error and you live a happy and easy life. We all know an SSRS report can easily ping your server to 100% CPU if you decide to export a 120 page report, to PDF,  with charts, etc. etc. You may get a complaint that performance suffers in another application while running the reports and you want to fix it, but do not know how.

To cut short I will copy these lines straight from  wiki  : “SQL Server ensures that any change to the data is ACID-compliant, i.e., it uses transactions to ensure that any operation either totally completes or is undone if fails, but never leaves the database in an intermediate state. Using transactions, a sequence of actions can be grouped together, with the guarantee that either all actions will succeed or none will. SQL Server implements transactions using a write-ahead log. Any changes made to any page will update the in-memory cache of ...
