Good afternoon everyone, One of the scenarios of the "Diagnostic Policy Service" always crashes when DPS tries to process it. This creates many errors in the event viewer. This is on Vista Home Basic. It's always scenario {739FF6CF-5033-428C-9E2F-582096482DD5}. What is this scenario and how can I fix this ? For your reference, I'veappended the error message below: Diagnostic module {C0F51D84-11B9-4E74-B083-99F11BA2DB0A} (%windir%\system32\radardt.dll) encountered an error while handling scenario {739FF6CF-5033-428C-9E2F-582096482DD5}, instance {91DBE11E-0D91-4C8C-9C1D-99748374D11B}, original activity ID {00000000-0000-0000-0000-000000000000}. The error code was -2147467259. (event ID: 170, source: Diagnosis-DPS, Task Category: Scenario Lifecycle) I can't find this error anywhere in Knowledge base or google. Thanks for your insight. Sincerely, Paul
