Hi,
Till you have these entry maintained in the host file it should not be an issue.
1476386 - Wrong localhost name resolution setting
1872990 - various error messages related to incorrect resolution of localhost
so as you have already maintained this entry.
x.x.x.x (Local host name)
x.x.x.x (Local host name.domain.com)
Did you try to restart the server after that and then try to start back the system again manually using sidadm.
hope firewall settings is disable on the server.
Thanks
Rishi Abrol
