Hello everyone, The SCOM environment includes a separate SQL Server 2005 server with SQL Reporting services installed.I'm following this article to working with Report Builder. This server is acting as reporting server for SCOM. When working on a custom report; in SQL Reporting Services Report builder; "Filter Data" option from "Report" menu displays a dialog box. On this dialog box when I select entity of type "Class", drag and drop "Class default Name" in right side pane and click "no values selected" underline text to bring up list of available classes to choose "Windows Computer" from... I encounter following error: What could possibly be wrong with report server? Please help.
