LAN issues after upgrade & Homegroup no longer exists

Hello,

My office upgraded from Win 7 to Win 10 about 3 months ago. Since then we've been having one heckuva time with our networking - we can no longer print to each others' printers, most of us can no longer access shared files, and while we used to have a Homegroup that was created on my computer several years ago, when attempting to manage the Homegroup, it says one was created, but doesn't give me an option to view the password.

I've spent the past few months searching for and trying a myriad of fixes, but have made no progress in resolving these issues.

Can you remove homegroup its not needed and was a mess from the start as long as your all in the same workgroup and subnet you can connect without it it uses ipv6 which adds network traffic

The homegroup is not there - that's part of the problem. Can't see a password because it isn't there. It just says there's a homegroup. Our network is on a switch vs a server.
