Hi everybody! I'm running a samba4 ad domain (samba-4.18.5) with two domain controllers and when I added the reverse lookup for my domain using samba-tool it created the SOA record for the zone with just one of the DC's. Using the AD DNS tools from RSAT in a windows 7 workstation I modified the SOA record to include the second DC and since then I have a folder icon that hangs from the reverse zone which says "com", if I click this folder the icon changes to a folder with an error icon (a cross in red circle) and if I right click the folder and try to delete it a get an error that states that the function is not compatible with the system. Everything seems to be working fine but I was wondering if there could be a problem I'm not seeing and if there is a way to get rid of that folder icon. Thanks in advance. Best regards, Dave.
