The remote name could not be resolved (Microsoft.SqlServer.Management.UI.RSClient)

When connecting to Reporting Services through SQL Server Management Studio (SSMS) you may receive the error:

The remote name could not be resolved: xxx (Microsoft.SqlServer.Management.UI.RSClient).

This error may be caused as a result of modifying the machine name.

In order to resolve the error you need to ensure that the element http://localhost/reportserver in the rsreportserver.config is configured to the correct computer name.

By default the rsreportserver.config file is in the directory C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\.
