Cannot access my own files on my network 0x80070035

I would reset all of the network settings on all computers that are on the network and then set everything as a Workfroup then manually change the sharing permissions. That Homegroup setup can't be trusted to stay stable over time. I have seen funny things happen with Homegoup time and time again. Printers dropping off the network for no reason, some client computers can't access certain files all of a sudden. Everything might be stable for awhile then issue begin.
