I've tried the fix in 
https://bugzilla.samba.org/show_bug.cgi?id=15418#c25 and it worked for 
us too.

After deploying a patched version of samba 4.18.4 to our DCs Ive tested 
2 win10 machins.

Machine 1: the "Test-ComputerSecureChannel" still showed false.

Calling the command with flag "-Repair" in an administrator-level 
powershell resulted in true and the test now shows true.

Re-enabled the NLA for RDP and it still works.

Machine 2: the "Test-ComputerSecureChannel" also still showed false. 
"-Repair" didnt work, because it couldnt find the computer account in 
the domain?! Using RSAT I could confirm that the user exists with a 
different name but the pre-2000 name was the correct one.

Deleted this user and recreated it in RSAT without a password.

After a lot of "Test-ComputerSecureChannel -Repair" and 
"Reset-ComputerMachinePassword" it finally worked and the secure channel 
is once again functional. Connecting to a SMB share via IP and a 
username without Domain-prefix worked.

Gonna rollout the patched versions to all DCs now and re-enable NLA and 
updates on all Win10 machines.

TLDR: +1 for me!

Thanks everybody, Matthias Kühne.
