Safe next steps
- For 6845 (ERROR_TM_IDENTITY_MISMATCH), record the exact option, parameter, object, or state mentioned by the message and the application that supplied it.
- Compare that value with the app vendor’s documented requirements. A generic registry edit or security bypass is not justified by the number alone.
- If it is an API return value, the developer should inspect the failing call and nearby logs.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
