Problem Viewing QOE and CDR Reports

In our internal environment randomly the Monitoring and CDR Reports randomly stopped working. After some troubleshooting and help from Google translator:

We were able to verify that the RTCReportPack account did not have “Allow Log on Locally” on the SQL Server.

After clicking to generate a report we would see this error:


  • An error has occurred during report processing. (rsProcessingAborted)
  • Cannot impersonate user for data source ‘CDRDB. (rsErrorImpersonatingUser)
  • Logon failed. (rsLogonFailed)
  • For more information about this error navigate to the report server on the local server machine, or enable remote errors.

    After adding the RTCReportPack account to the Allow Logon Locally group in the local security policy this went away.
