I have the same problem, but Im not using Veeam.. Im using DPM
I have also got the refs.sys file from a MS technician, but my issue is when Im replacing the existing refs.sys the disk is reported RAW and can not be read.
Any special order/rutine to change the file that my technician has not mentioned?
Did you put your system into test signing mode?
No, I got no instructions of doing so.
But I tried that on a test VM that I created and after a reboot it felt like the server became 100 times faster and I was able to access the disk.
I have asked the technician for a new file but I guess that wont help since the file isnt signed. Also, if you check properties on the refs.sys you will see a "certificate error" and that is since it isnt signed (duh).
Thanks for the help!
by the way, I opened my case with MS late April and it took a while to get here...
