I'm trying to setup a new computer on my office network and can't enable file and printer sharing. I've tried a lot of things I've found in the posts on this site but no luck. When I click Turn on File and Printer Sharing and save it doesn't give me the expected requester confirming I want to make the change but just closes out normally. When I go back to check it it is unchecked again. I've spent two days trying to find the answer. A lot of posts made reference to issues with the firewall. I had McCaffee which I eventually uninstalled after so many attempts with the settings to use the windows firewall. Didn't work. I shut down Windows Firewall and defender just to see if it might be that and I have the same thing. I'm really stuck now hopefully someone can help.
