Cognos Error: DPR-ERR-2056

Account Structure Reports IBM Cognos 8
DPR-ERR-2056 The Report Server is not responding.

User launches any standard report (also known as “system report”). For example, user launches “Maintain - Account Structure - Reports” and selects a report. The report window displays, but inside there is an error message.

There are many different potential causes for this error message.
Often a “corrupt” installation media is causing this issue. This has some missing files, which means that there are not the required DLL files available for the BiBus process to launch correctly (when the report runs).

1. Re-download the Controller installation media from the IBM website
2. Re-extract the file
3. Finally, uninstall Controller and then re-install using the new installation media files/folder.
