Heya, Ned here again. Storage Migration Service admins: if you’re seeing “Error HRESULT E_FAIL has been returned from a call to a COM component” during transfer validation after installing the November cumulative update, we have a workaround coming to WAC, watch for it to appear next 48 hours. Once you get it, you will be able to ignore the error (which is bogus) and proceed with transfer; this will allow us time to diagnose the real issue and have a real fix inside the Orchestrator itself. We still cannot reproduce this issue ourselves and suspect some networking environment issue in a small subset of customer environments.
Do not uninstall the November update as a workaround. I say again, do NOT do that. The update upgrades your database and cannot be reversed without deleting the DB.
– Ned “Hang in there” Pyle
