SMB Windows10 and Windows server 2008R2?

Question

Samba

Hello!
There is a Windows Server 2008R2 with shared folders and there are Windows 10 clients
On the server, all versions of SMB are enabled, as on 10s, but I see balls only from the server to machines, but I can’t get from machines to the server, the standard error is "The network location is not discovered" or something like that.
Previously, it was solved by enabling SMB 1 on Windows 8-10 versions, but it did not help in this situation.
Network discovery and other "default" things are included.
Tell me where to dig, please

Answer 1

Domain or just locale?
If it's just a locale, then in local policies I remember you need to disable the guest account so that access via // works. Check all the parameters that start with "Network access - ...."
Well, I would probably post some logs, a tab with rights on the server folder, etc. Does the tracert go to the car at all? Maybe there is no ping, or the firewall blocks old SMB versions. There to mine under 2 and 3 versions separate rules.

Answer 2

In general, I raised a similar system on a virtual machine, set up the balls, it worked.
Transferred all settings of policies, registry, firewall to a non-working server. Didn't work. I changed the role, it didn't work.
Desperate, picked it all up again. I should have tried System Restore, but didn't even think about it.
In general, everything is ok out of the box. Most likely, after a power outage, the system broke down, and then half of the drivers then flew off.
