SSRS : Changing PC Name
If you are using SQL Server Reporting Services (SSRS) as a reporting solution, and must change your device's PC name, SSRS may not correctly generate and display reports once the computer has been renamed. To correct this, perform the following steps: Open the Reporting Services Configuration Manager. Click the Database Tab. Modify the existing database, and simply follow the prompts. Once the procedures and steps are completed, try to re-run your Reports.
