SSRS in SharePoint Integrated Mode Error

Hi,

We have a requirement for creating SSRS report using SharePoint 2010 List as a data source.  We have two WFEs and one database server and we have followed below steps.

1. Installed SSRS add-in on both WFEs
2. Configured and setup SSRS on one of the WFEs
3. Configured SSRS in Central admin of SharePoint 2010

We are downloading report builder from SharePoint 2010 document library and creating the reports, but the problem is while we are publishing, Report builder is throwing error and we tried to google but we have not yet got any resolution.

Error:

For more information about this error navigate to the report server on the local server machine, or enable remote errors

----------------------------

The URL, 'http://testportal/sites/OutageUAT/_vti_bin/reportserver', cannot be mapped to a public URL in this SharePoint environment. (rsUrlRemapError)

Please let us know if you have come across this issue and have found any resolution as it may help us to solve and publish the reports.

Regards,

Sudheer
