This just started in the last couple of weeks, up until then everything was fine... Win 7 machines don't seem to be affected, but 3 of our tech's Win 10 machines cannot backup now and no one has made any significant changes in software. And the backup doesn't just fail, it goes along to about 80% like normal and then the entire programmer just closes, like someone force closed it in Task Manager. I even tried it on my "RMAT PC" which is a NUC in the data closet that we can remote into so any remote maintenance appears to be coming from our companies IP address, and that one is the same. Tried about 5 or 6 different locations and the result was the same every time, although the exact place it stops does vary a little.
