how to give Anonymous access to reports

I have window server2008 on which i have remote access.

Using report builder tool we have created a report named PopulationReport.

When i take the remote access using my domain profile and hit the URL

"http://ServerIP/ReportServer/Pages/ReportViewer.aspx?/New20开发者_高级运维Folder/PopulationReport&rs:Command=Render&rs:Format=Excel"

It provides the report in excel format.

but when hit the url using some other machine it demands the domain Credentials.

How can i make this URL open(or say public) or at least a system on the same network(LAN) can access it.

It is necessary to ensure trust between the reporting system and the other users who do not belong to your domain. In my case, I made ​​rolle database related to specific audiences or their IP address, works fine.
