How do I setup network to share files since homegroup is no longer

I have a problem very close to yours.  I hope somebody sheds some light.

Starting with the build that eliminated Homegroups, I have been unable to share files and folder on my home network by any method.  I've checked all the sharing options in the folders and in Windows Networking settings and don't see anything amiss.  I did notice, however, that the services Lanman Server and Lanman Workstation (? not sure of the name) are now missing from the services list.

If anybody can confirm this is a bug, please do so!  If this is just MY problem, it happened simultaneously on all four of my Win10 computers.  All four see only my Win7 machine on the network, but Windows says I don't have permission to access it.  My Win7 machine sees all of the computers, but gets the same "no permission" message when I try to access them.
