[SQL Reporting Service] Deploy sql reporting service to another Project server 2010

Hi everyone,

I install sharepoint server 2010 & project server 2010 and create a pwa site.

I create a sql reporting service in my server and test successfully. I deploy it to pwa site by way: "- create a document library in pwa site - from this document library , add new item, browse to a *.rdl file and choose it - then, show report successfully".

And I use this way to deploy to another server. I see error when I test it. Although, I change the connection string correctly. That is "Error. The request failed with HTTP status 401: Unauthorized."

Do you have some opinions?

I wish I would see your response soon.

Thanks and Regards,

An Pham
