edit: My problem was with the host computer and password protected sharing being on and I could not turn it off. I found my answer which involved deleting the password for a guest account (?). It worked and now I have access to that computer but frankly there are still issues as I don't always see every computer on my network even though I enabled the needed services. I solved this by creating shortcuts to specific computers. Lots of workarounds for something that previously worked fine with Homegroups.
I am so lost. I am able to see my networked computers but I can not access files from them. I enabled sharing but if I try to access I get "Windows can not access... You do not have permission to access. Contact your network administrator..."
Homegroups previously worked fine. Thank you Microsoft for destroying my computer experience.
