[Samba] Samba 4.8 RODC not working

Hi Rowland, 


I have no homes share. As far as I know I should not have that share on a DC ..? 


Regarding the security consideration for a DMZ zone, what do you suggest instead of putting a RODC in it ? 


Note : Yes I can ping DC, there is no routing / firewalling issue (validated). 


Thanks

Not that it helps, but I have now notice why you want the RODC, you 
want to do something stupid like putting it into a DMZ zone. 
This is not recommended, it is a security risk. 

If you must do this, then do you have a share in smb.conf called 
'[homes]', if so, remove the trailing 's' i.e. make it '[home]' and 
read the wiki. 

Running out of ideas now, except, can you ping a DC from the RODC ?
