Question : 2005 Reporting Services Permissions Error

When trying to deploy reports for the first time on this box (Windows 2008 Server 64bit) i get the error: "Deploying to http://localhost:81/reportserver
Error rsAccessDenied : The permissions granted to user 'NT AUTHORITY\NETWORK SERVICE' are insufficient for performing this operation."

I'm using II7, Windows 2008 Server, and of course 2005 SSRS.

Just before this I had to do a Init on the server using this command:
"C:\Program Files (x86)\Microsoft SQL Server\90\Tools\binn>rsconfig -c -sAA-2008-
SRV-STD -dReportServer -awindows"

Which worked to a point.  I can now get to the SSRS web services without a problem from the browser.  But I get this message when trying to access the  RS from the web (using Admin account) "http://localhost:81/ReportServer":

"The permissions granted to user 'NT AUTHORITY\IUSR' are insufficient for performing this operation. (rsAccessDenied)"

So, I can't deploy and I can get to the RS.

Thanks --

Answer : 2005 Reporting Services Permissions Error

I got it to work by running:  

First I the Report Server was not initialize and the following did the trick:
C:\Program Files (x86)\Microsoft SQL Server\90\Tools\binn>rsconfig -c -sAA-2008-
SRV-STD -dReportServer -awindows

Second:
From the error message, its caused by the permission issue. Please right click on My Computer icon, and choose Manage, and then you can see the computer management window, in the left treeview, expand the Local Users and Groups node, and click on Groups, try to find SQLServer2005ReportingServiceWebServiceUser$MachineName$InstanceName and SQL2005ReportServerUser$MachineName$InstanceName, right click on both groups and choose Properties, make sure that if 'NT AUTHORITY\NETWORK SERVICE' user has been added to these groups.

This allowed me to see: localhost:81/ReportServer and deploy the reports to the urls posted in the above pictures.

This also allowed me to see the deployed reports in Report Manager: http://localhost:81/Reports

Finally:
But then I ran into another problem with access to encryped data when I tried to run the reports in the Report Viewer.
The follwing fixed this issue:
rsconfig -eMY_DOMAIN_NAME\Administrator
