In my companies facility we are in the process of changing our IP scheme from a 165.154.67/24 network to a 10.0/16 network. I have a cisco router with to ethernet cards so that all servers and peripherals can pass traffic bewtween the two networks. The problem I am having is with one Server which is on the 165.154.67 segment not being able to ping servers on the 10. segment by name. Now I have other servers on the 165.154.67 segment that can ping servers by name on the 10 segment with no problems. The difference be the one that cannot and the one that can is that the one that cannot is not part of my companies domain but the ones that can are. One of my co-workers says that we have a DNS problem. He says that the Server on the 165.154.67 segment that is not part of the domain should be able to ping servers on the 10 segment, and I say just the opposite. Do I indded have a DNS problem or am I correct by stating the problem is caused by this server not being part of the domain.
