I know this is already asked but I can't find a clear answer. I put a new Ubuntu server in my LAN and I can't ping it but the hostname. I don't want to edit all my LAN windows hosts's file (+40 pcs) and add the entry. Perhaps I have another Ubuntu server and I can ping it by hostname without change anything.
All servers and client are using another internal DNS server based on an old redhat installation.
The hostname in the server that I can't ping is setted. What I have to do/check?
