Urgent Please: Cannot publish Reports to the Sharepoint Integrated - Reporting Services Login

Question

Hi,
Sharepoint 2010 / SQL Server 2008 R2
The user I am using in BIDS to deploy the reports has Admin permission to the site collection and databases.
Reporting Services Login prompt all times and I can´t go ahead to publish the reports.
I ve reviewed my deployment properties -
http://msdn.microsoft.com/en-us/library/bb283155(SQL.90).aspx
The same test works to my dedicated server (Sharepoint and SQL Server in the same machine) but not to the enviorement bellow:
Server 1 - SSED, SSAS, SSRS, Sharepoint Web Front (minimal installation)
Server 2 - Sharepoint Server 2010 (SSRS Sharepoint Integration Mode)
I´ve read all the discussions and articles I couldn´t find anything conclusive.
Please, any clues?!
Thanks in advance,

Hi Syed, thank you so much for your help. I have already spent many hours in order to solve this issue but nothing so far.
The Web Application I created to test it has a Business Intellicente Center as Site Collection. The Report Services features is running on it. I checked it. Thanks.
Follow more details I ´ve discovered:
Here's the scenario:
I have a Web Front End (WFE) server, and an Application Server (AS) in a Sharepoint 2010 Farm.  The configuration database, content database, etc.. are located on a clustered SQL 2008 R2 instance on another set of machines.  I have installed SQL
2008 R2 Reporting Services w SP1 on the AS.  I have installed the SQL 2008 Reporting Services Add-In for Sharepoint 2010 on the WFE.  I have gone through all the configuraiton settings, set the SPNs for the service accounts, etc... The Excel Services
with external data, for example, is working fine.
When the reporting services integration is set to "Trusted Account", I can deploy reports to the server with no problem, EXCEPT that I can't deploy data sources that use "Windows Authentication" as their credentials, which is desirable for our implementation.
When I switch the reporting services instance to "Windows Authentication", I can no longer deploy projects to the report server.  When I go to deploy the reports, I continually get a "Reporting Services Login" prompt, showing the server it is being deployed
to, and requesting a username and password.  No combination of username and password works.
Here's a fun little bit for you too, if I continue to try to login to the server, I will eventually (after hitting the GPO threshold) lock out my account from Active Directory.  This I found out after nearly creating a set of tracks down my scalp all
day today trying to figure out what was happening to my sharepoint sites while I was debugging this....
So it seems that it is trying to authenticate my login credentials through BIDS, but is unable to do so.
Also, when I attempt to "Manage Datasource" directly through the Sharepoint interface I am getting 401 errors.
I appreciate any assistance.
Thanks a lot.
