Internal name resolution set up for mixed server environment
Posted on 2003-03-20
I don't know if I may be missing some fundamental common sense right now but I need some help. I support a client network that is a group of standalone servers, mostly Win2000 Server but some Solaris and a couple of NT 4.0's still hanging around. Currently they host their own DNS servers. The servers within the network point to these two servers for their own DNS resolution as well.
They will be switching over to a hosted DNS service. The servers currently exist on various network segments interconnected by a firewall. There are some proprietary applications on the servers that connect to other servers across the network segments. Currently some of these applications have setup parameters that talk to the other servers by their FQDN. For example, within the code itself it will say "create socket with server.company.com on port xxxxx".
My question is... once we flip over to the hosted DNS what should I do about internal name resolution? Do I set up DNS on one of the servers and add all of the entries or do I point the servers to the external name servers? I feel as though I must be missing the obvious here but I am not sure how to proceed. Any suggestions would be appreciated.
