Hi, I've been using a Samba based AD for a while and things are going more or less okay. I did have to turn off my second (samba) AD however as I couldn't get synchronisation working properly. Lately however I've been having issues trying to manage the domain using RSAT on Windows 7. When I try to open Group Policy Management I get a dialog box stating "The RPC server is unavailable". Also adding a Windows 10 pc to the domain fails with "Can't join this domain. Contact your IT admin for more info", sigh. I am not even able to unjoin a Windows 7 pc from the domain. Fortunately authentication against AD still works fine. Any idea what may be causing this?
