Cause

This issue is tied to the Hardware Health Overview widget and the files/resources it loads while rendering Hardware Health data on the Group Details page. When the widget is triggered for groups containing Hardware Health data, the Group Hardware Health render path can fail with Resource Key 'HHLIBCODE_DOY_10' was not found in Resource File 'HardwareHealth.Strings'. The failure occurs in the web rendering layer, not as a generic IIS crash.

  2. Navigate to the affected Group Details page.
  3. Edit the detailed Group Details dashboard.
  4. Remove the Hardware Health Overview widget.
  5. Save the dashboard changes.
  6. Re-add the Hardware Health Overview widget to the same detailed Group Details dashboard.
  7. Save the dashboard again.
  8. Reopen the Group Details page and confirm it now loads normally for the affected group.
