This is probably a stupid question but I am finding a tricky issue on my Solaris machines right now. I changed the hostname for my servers as requested by my superior. I had one server that lost it's entire network configuration when I rebooted. I reconfigured it with it's address and I can access it. BUT, now the developer cannot reach any of the 3 servers. I can reach them but I reach them via an internal address 192.168.x.x and he accesses them via a VPN using an external address 172.x.x.0. I did not change the IP address, only the hostname. I did think about DNS but we don't access those servers via DNS hostname.
Is there a file i'm missing I need to check to see the addressing scheme for the 172.x.x.x address? I know we have other Solaris machines with external addressing, but I cannot find their external addressing definition.
