Deploy ssrs reports on report manager (2008 R2)

Hi,

I have installed SQL Server 2008 R2 enterprise version on my system,  created reports from BIDS (with shared Data dource) and trying to deploy reports on my report manager. But , it was saying report server url is not found. I have used default report manager url.

Can someone help, how to deploy the SSRS reports that i have developed from Visual studio (client) to report manager using native mode?

Thanks
