Unable to Generate Reports After Migration

Symptom​

After migration, some Netwrix Auditor reports are generating the following error:

Unable to cast object of type 'System.Guid' to type 'System.String'

Cause​

Some files were corrupted in the Reports folder after migration.

Resolution​

  1. In Netwrix Auditor, navigate to Settings > Audit Database.
  2. Open the Report Manager URL to access the SQL Server Reporting Services (SSRS) site.
  3. Remove the Netwrix Auditor root folder in SSRS.
  4. On the computer that hosts the Auditor Server, open the Services snap-in. You can do this by searching for Services.
  5. Restart the Netwrix Auditor Management Service. This will recreate the reports folder and resolve the error. The reports will take 5-10 minutes to re-upload.
