Hi I have a Samba4 setup of 2 DC's running 4.7.4 and RODC's running 4.7.4 on the sites. Now I have a problem with a WIN 7 client at the remote location who logs on the RODC server and when I try to browse a Windows Network share using the \\Hostname it gives out the below error : "The System has detected a possible attempts to compromise security. Please ensure you can contact the server which authenticated you" But when I try to open the same share with the \\IP address it works without any error. I have preload the Client computer and the domain user on the RODC.
