WUDFRd failed to load

NTDEV
1

Hi,

I am seeing a warning in the event log which basically says “WudfRd
fails to load for the device xxx” (where xxx is my device). This
warning seems to be there for other devices as well.

Everything seems to be working fine even though this warning is in the
logs but my customer needs to know what all this is about and I have
no clue. Well I have one theory, which is that WudfRd tries to start
before my device is loaded and hence fails, everything will work fine
later on since it will try to load again.

Does anyone have an idea of what these warnings are about? Why is
WUDFRd failing to load on my device? Can I do something to avoid them?

Also, (maybe not related but it sure seems so) there is an Information
event logged just before the warning which says “The UMDF reflector
was unable to complete startup because the WUDFPf service was not
found. The service may be started later…”

Thanks,

Faik

Hi Faik,

If your device is up and running without any issues, it’s safe to ignore these warning messages. These warning messages are being logged maybe because the service that WudfRd depends on did not start on time. And once the service starts, it will attempt to re-start all the devices. AFAIK, there isn’t a way to avoid these warning messages.
