First im Using SQL server 2014
Reporting Services Configuration Manager
Goto Service Account -->
Change Use build in account
to Use another account
after restart the sql Server reorting services i got this message below.
I try rsactivate
C:\Program Files\Microsoft SQL Server\80\Tools\Binn
rsactivate -r -c "C:\Program Files\Microsoft SQL Server\MSSQL\Reporting Services\ReportServer\RSReportServer.config"
But its showing rsactivate is not recogninized
Error rsReportServerDisabled: The report server cannot decrypt the symmetric key used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted content and then restart the service.
Can some one help me to solve this issue.thx
