Network mess after last creator update

With the last update Microsoft created areal network mess.
Before the update I could see and access all shared folders on the connected PC's in the LAN .
Now I don't see them most of the time or disappear after a while, but the most strange thing is that when I the other
PC's shared folders listed under "Network" are visible and accessible, the listed shares from folders on the PC that I am
working on are NOT accessible at all.

After clicking the share, Explorer shows (no respons) in the title bar, meanwhile the cursor shows being busy and the after more than 40 seconds an Network error message shows. No acces to \\PCNAME\Music files
Error code: 0x80070035
Cannot find network path

Well, the creator update is a true creator, regarding the network a real mess

Renewed some of the shares, with access for everybody, RW and full management.
Now when clicking the listed shares under Network, the contents got listed, but....
after clicking one of the not renewed shares, long waiting until the error message and
then clicking one of the renewed that worked before, same problem occurs, message no access.

For now I give up, waiting until MS solves this mess

I would start by pinging said computer to verify it's up. Then try to connect to the share root \\COMPUTERNAME or \\IPADDRESS and verify the shares are visible.

Point is, it worked before without problems
I see the shares from other Pc's in the LAN and can access them.
What I cannot solve is the the shares on my working PC are visible under "Network"
but when trying to acces by clicking on them I get the error.
From the other PC's in the LAN \\MYCOMPUTER is visible but not the shares, while they were accesible
before this last "creative" update.

Well if the computer with the shares is Vista or newer it won't be using SMBv1. A quick wireshark capture would tell us what smb version is in use with an smb or smb2 display filter.
