Windows 7 client can't access 2019 SMB share

well, title says it all I guess

We have recently commissioned a new Server 2019 file server and for some reason, our Win 7 workstations can't seem to access the shares.
We can ping the server. we can browse the share, We can authenticate. but after that we an "access denied" error message and a reprompt for a password (which will always fail)

Win10 and Mac OSX clients can connect and work without any issue.

We have tried to install SMB 1.0 services (that we don't want to use - was mostly out of desperation) to no avail.

Any idea/suggestion most welcome.

Win 7 enterprise + Server 2019 - all patch applied.

Domain or else?

What does the Windows event logs say on your Win 7 clients as well on the server?

Guest/Anonymous access is blocked per GPO (ComputerConfiguration\Administrative Templates\Network\Lanman .Workstation "Enable insecure guest logons") on the server.

p.s. Win 7 has an support end date next February..
There is a possible solution near the end of this post

It is roughly the same as the post above.   So that is what you need to try.
