Hi,

Thank you so much for the reply and great suggestion!

At last I found what was the issue with the blank page... It was mode of authentication which was set to Windows Negotiate instead of NTLM.

In Reporting Services Server, there is a config file “reportserver.xml” located in "\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\"

In this file there is a line specified authentication mode which for us was set to

•windows negotiate first priority

•NTLM second priority

To solve the issue I just removed windows negotiate!!!
